• ## RF CHECK Solution

### What is RF and microwave radiation?

Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. Taken together, all forms of electromagnetic energy are referred to as the electromagnetic "spectrum." Radio waves and microwaves emitted by transmitting antennas are one form of electromagnetic energy. They are collectively referred to as "radiofrequency" or "RF" energy or radiation. Often the term "electromagnetic field" or "radiofrequency field" may be used to indicate the presence of electromagnetic or RF energy.

The RF waves emanating from an antenna are generated by the movement of electrical charges in the antenna. Electromagnetic waves can be characterized by a wavelength and a frequency. The wavelength is the distance covered by one complete cycle of the electromagnetic wave, while the frequency is the number of electromagnetic waves passing a given point in one second. The frequency of an RF signal is usually expressed in terms of a unit called the "hertz" (abbreviated "Hz"). One Hz equals one cycle per second. One megahertz ("MHz") equals one million cycles per second.

Different forms of electromagnetic energy are categorized by their wavelengths and frequencies. The RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz). Microwaves are a specific category of radio waves that can be defined as radiofrequency energy where frequencies range from several hundred MHz to several GHz.

"Ionization" is a process by which electrons are stripped from atoms and molecules. This process can produce molecular changes that can lead to damage in biological tissue, including effects on DNA, the genetic material. This process requires interaction with high levels of electromagnetic energy. Those types of electromagnetic radiation with enough energy to ionize biological material include X-radiation and gamma radiation. Therefore, X-rays and gamma rays are examples of ionizing radiation.

The energy levels associated with RF and microwave radiation, on the other hand, are not great enough to cause the ionization of atoms and molecules and RF energy, therefore, is a type of non-ionizing radiation. Other types of non-ionizing radiation include visible light, infrared radiation and other forms of electromagnetic radiation with relatively low frequencies. Often the term "radiation" is used to apply to ionizing radiation such as that associated with nuclear power plants. Ionizing radiation should not be confused with the lower-energy, non-ionizing, radiation with respect to possible biological effects, since the mechanisms of action are quite different.

### How is RF radiation used?

The most important use of RF radiation is for telecommunications. Radio and TV broadcasting, wireless phones, pagers, cordless phones, police and fire department radios, point-to-point links and satellite communications all rely on RF radiation.

Other uses of RF radiation include microwave ovens, radar, industrial heaters and sealers, and medical treatments.

### How is RF radiation measured?

RF waves and RF fields have both electrical and magnetic components. It is often convenient to express the strength of the RF field in terms of each component. For example, the unit "volts per meter" (V/m) is used to measure the electric field strength, and the unit "amperes per meter" (A/m) is used to express the magnetic field strength. Another common way to characterize an RF field is by means of the power density. Power density is defined as power per unit area. For example, power density can be expressed in terms of milliwatts (one thousandth of a watt) per square centimeter (mW/cm2) or microwatts (one millionth of a watt) per square centimeter (µW/cm2).

The quantity used to measure how much RF radiation is actually absorbed by the body is called the Specific Absorption Rate or SAR. The SAR is a measure of the rate of absorption of RF radiation. It is usually expressed in units of watts per kilogram (W/kg) or milliwatts per gram (mW/g).

### Is RF radiation hazardous to humans?

Biological effects can result from animal or human exposure to RF energy. Biological effects that result from heating of tissue by RF energy are often referred to as "thermal" effects. It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. This is the principle by which microwave ovens cook food. Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature. Tissue damage in humans could occur during exposure to high RF levels because of the body's inability to cope with or dissipate the excessive heat that could be generated. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because of the relative lack of available blood flow to dissipate the excessive heat load.

At lower levels of exposure to RF radiation (i.e., levels lower than those that would produce significant heating) scientific evidence exists of harmful biological "non-thermal" effects. It is the scientific studies of non-thermal, behavioral/cognitive/psychological injuries upon which the Federal Communications Commission (FCC) RF radiation human exposure limits are based.

## Laws RF Radiation & Regulations

### Do any laws exist that are intended to protect individuals from RF radiation?

The Telecommunications Act of 1996 (47 USC 224) established the Federal Communication Commission’s (FCC’s) preeminent role in the creation of RF radiation exposure standards.

In this vein, the FCC has established two sets of RF radiation exposure limits - “Occupational/Controlled” and “General Population/Uncontrolled”. The less restrictive Occupational/Controlled limits only apply when a person (worker) is exposed as a consequence of his or her employment and is “fully aware of the potential exposure and can exercise control over their exposure,” otherwise the General Population limits apply. 47 CFR 1.1310.

The FCC exposure limits apply to all FCC licensed facilities. 47 CFR 1.1307(b)(1). As a condition for obtaining a license to transmit, a wireless carrier must certify that it complies with FCC environmental rules including those that are designed to prevent exposing persons above FCC RF radiation limits. 47 CFR 1.1307(b).

Licensees at co-located sites must take “actions necessary” to bring the accessible areas that exceed the FCC exposure limits into compliance. This is a shared responsibility of all licensees whose transmission power density levels account for 5% or more of the applicable FCC exposure limit. 47CFR 1.1307(b)(3).

Failure to comply with the FCC rules regarding human exposure limits can subject a licensee to fines, loss of license and denial of license renewals. 47 CFR 1.80.

### Are there other Federal RF radiation regulations?

Federal OSHA demands that employers provide a workplace free of recognized hazards which may cause serious harm. RF radiation exposure in excess of the FCC limits is a recognized hazard (OSHA General Duty Clause). 29 U.S.C. 654, § 5(a)(1).

Employers in the telecommunications industry must implement elements of an antenna safety program including worker training, signage, and procedures that prevent employees from exposure in excess of the OSHA RF radiation exposure guidelines. 29 CFR 1910.268.

Under certain conditions, Service Providers may be in violation of OSHA standards when their antenna emissions expose an employee of another employer above the OSHA RF radiation exposure limits pursuant to the OSHA “Multi-Employer Worksite Policy.” CPL2-0.124.

Similarly, construction employers must provide safety programs, including frequent inspections and training, which protect workers from all hazards, including RF radiation hazards. 29 CFR 1926.20(b)(1); 29 CFR 1926.54.

However, this requirement does not remove the legal obligation of an FCC licensee to ensure its antenna emissions do not expose persons above the FCC limits (i.e., FCC licensees must prevent excessive RF radiation exposures even if a construction employer fails to protect its workers from RF radiation).

### Do any state RF radiation regulations exist?

In addition to the general obligation to provide a safe work environment, most states have enacted standards to protect public workers which are either the same or even more protective than federal OSHA standards.

For example, California has enacted Cal-OSHA which establishes maximum permissible RF radiation exposure limits for workers [Title 8, Section 5085 (b)], imposes RF radiation signage requirements [Title 8, Section 5085 (c)], demands a program to control hazardous energy from antennas during maintenance in locations otherwise causing excessive RF radiation exposures including an annual audit of the program [Title 8, Section 3314] and mandates the implementation of a written Injury and Illness Prevention Program [Title 8, Sections 1509 and 3203].

The Cal-OSHA defines “employer” as “(1) the State and every State agency; (2) each county, city, district and all public and quasi-public agencies therein; (3) every person, including any public service corporation which has any natural person in service; (4) any Conveyance Owner…and (5) any employer who employs ‘affected employees’ as defined by Rule 403(l).” [Title 8, Section 403 (n)]

Cal-OSHA expansively identifies potentially culpable employers in the context of multi-employer worksites as follows:

“On multi-employer worksites, both construction and non-construction, citations may be issued only to the following categories of employers when the Division has evidence that an employee was exposed to a hazard in violation of any requirement enforceable by the Division:

1. The employer whose employees were exposed to hazard (the exposing employer);
2. The employer who actually created the hazard (the creating employer);
3. The employer who was responsible, by contract or through actual practice, for safety and health conditions on the worksite; i.e., the employer who had the authority for ensuring that the hazardous condition is corrected (the controlling employer); or
4. The employer who had the responsibility for actually correcting the hazard (the correcting employer).” [Title 8, Section 336.10]

“Employers” listed in subsections (b) through (d), supra, may be cited despite the fact that their own employees were not exposed to a hazard.

### Is there science supporting RF radiation being harmful to humans?

The Federal Communications Commission (FCC) recognizes RF radiation as a known health and safety hazard. As a result, it has established RF radiation regulations and human exposure limits to protect workers and the general public. The science upon which the FCC regulations are based is long-standing, uncontroverted and not the subject of any dispute. (1)

The science has clearly demonstrated that RF radiation exposure causes “behavioral disruption” in laboratory subjects. Behavioral disruption is the inability to perform food-motivated learned behavior. The inability to perform learned tasks following RF radiation exposure proves the causal link between the exposure and behavioral, cognitive and/or psychological injuries which include depression, memory loss, mood disorders, sleep disorders and impaired or diminished cognitive function.(2)

### Is there any ongoing Congressional investigation on the adverse health effects of RF radiation?

On November 3, 2008, Representative Dennis Kucinich, Chairman of the Domestic Policy Subcommittee, sent a letter asking FCC Chairman Kevin Martin to consider the potential health effects before voting on an Order that would authorize the use of the ‘White Space’ spectrum for wireless devices operating in the home. Skeptics have expressed concern that the use of the White Space spectrum would result in the repeated and long-term exposure to RF radiation, to which the human health effects are not adequately known. On November 4th, 2008, the FCC adopted the Second Report and Order, which allowed such use.

In September and October 2008, Representative Kucinich also chaired a hearing on the adverse health effects of wireless technology.

As public concern remains and grows, additional hearings and investigations are foreseeable.

### What is RF radiation overexposure?

An RF radiation overexposure occurs when an individual is subject to RF radiation emissions that exceed, or are in violation of, the FCC RF radiation human exposure limits.

### What does it feel like to be overexposed to RF radiation?

RF radiation overexposure can result in thermal and non-thermal injuries. In instances of an overexposure resulting in thermal injuries, the individual will experience a heating or burning sensation. However, in the case of a non-thermal injury, the individual may not be immediately aware of any sensation. In other words, an overexposure may be undetectable at the time of occurrence.

### Can RF radiation be sensed through touch, taste, smell, sound, or sight?

The danger and health and safety risk of RF radiation is that, absent a thermal injury, it cannot be identified by human sensory functions such as touch, taste, smell, sound or sight. An individual may sustain a non-thermal injury and not realize that he or she has been subjected to an overexposure at the time.

### Is RF radiation overexposure dangerous?

Yes, there may be situations, particularly workplace environments near RF radiation sources, where recommended limits for safe exposure of human beings to RF energy could be exceeded. The FCC and OSHA human exposure limits must be observed for the safety of all workers and the general public.

## RF Radiation Exposure at Wireless Sites

### Are cellular towers and RF radiation transmitting antennas safe?

Cellular radio services transmit using frequencies between 824 and 894 megahertz (MHz). Transmitters in the Personal Communications Service (PCS) use frequencies in the range of 1850-1990 MHz. Antennas used for cellular and PCS transmissions are typically located on towers, water tanks or other elevated structures including rooftops and the sides of buildings. The combination of antennas and associated electronic equipment is referred to as a cellular or PCS "base station" or "cell site." Typical heights for free-standing base station towers or structures are 50-200 feet. A cellular base station may utilize several "omni-directional" antennas that look like poles, 10 to 15 feet in length, although these types of antennas are less common in urbanized areas.

In urban and suburban areas, cellular and PCS service providers commonly use "sector" antennas for their base stations. These antennas are rectangular panels (e.g., about 1 by 4 feet in size) typically mounted on a rooftop or other structure, but they are also mounted on towers or poles. Panel antennas are usually arranged in three groups of three each.

At a given cell site, the total RF power that could be radiated by the antennas depends on the number of radio channels (transmitters) installed, the power of each transmitter, and the type of antenna. While it is theoretically possible for cell sites to radiate at very high power levels, the maximum power radiated in any direction usually does not exceed 50 watts.

The RF emissions from cellular or PCS base station antennas are generally directed toward the horizon in a relatively narrow pattern in the vertical plane. In the case of sector (panel) antennas, the pattern is fan-shaped, like a wedge cut from a pie. As with all forms of electromagnetic energy, the power density from the antenna decreases rapidly as one moves away from the antenna. Consequently, ground-level exposures are much less than exposures if one were at the same height and directly in front of the antenna.

Measurements made near typical cellular and PCS installations, especially those with tower-mounted antennas, have shown that ground-level power densities are thousands of times less than the FCC's limits for safe exposure.

When cellular and PCS antennas are mounted at rooftop locations it is possible that a person could encounter RF levels far greater than those typically encountered on the ground. Exposures approaching or exceeding the safety guidelines are likely to be encountered close to and in front of the antennas.

The health and safety of workers such as electricians, roofers, painters, HVAC technicians, maintenance workers and members of similar trades are at risk when they are compelled to work in close proximity to RF radiation transmitting antennas. Today there are more than 600,000 commercial and governmental antennas across the United States. It is projected that in the near future this number will double. As a result, antennas are everywhere. They are on rooftops, the sides of buildings, billboards, utility poles, light standards, camouflaged and hidden entirely within the structure of buildings. In turn, the likelihood that workers will be compelled to be near and in front of RF radiation transmitting antennas is great.

### What can I do to protect myself from RF radiation at or near RF transmitters?

Unfortunately, no comprehensive RF radiation health and safety solution currently exists. Workers are, therefore, left vulnerable to potential RF radiation overexposures.

In the absence of a meaningful protocol and tools, workers must strive to protect themselves. All RF radiation signs should be observed to the extent possible. However, reliance upon signs may be unwarranted because signs are often missing, misplaced, ambiguous or outdated.

Workers should receive some RF radiation training and awareness to permit them to minimally identify the existence and location of an RF transmission source, as well as basic concepts of RF radiation safety.

If compelled to work near the antennas, the worker should request and obtain a power-down before beginning his or her work. However, obtaining and verifying the existence of a power-down may be problematic.

Practically speaking, the best action to protect oneself is to support RF CHECK and demand implementation of its comprehensive RF health and safety solution.

### Where are the most common places I can be overexposed to RF radiation?

Regrettably, a fundamentally flawed system exists to protect all workers and ensure compliance with applicable regulations. RF health and safety strategies that currently exist were developed in, and for, a bygone era. According to the wireless industry association, CTIA, in 1996 less than 23,000 wireless antennas were scattered throughout the United States. Today, there are hundreds of thousands of antenna sites, many with multiple (i.e., collocated) antennas. An estimated 600,000 commercial and governmental antennas exist across the nation, a number projected to double in coming years.

In the past, the limited number of antenna sites were isolated, could be fenced and access restricted to RF trained technicians. Today, antennas are everywhere. They are on rooftops, the sides of buildings, billboards, utility poles, light standards, camouflaged and hidden entirely within building structures. Dependent upon the particular trade or work to be performed, the risk of overexposure is great.

### Are the RF radiation emissions from my cell phone the same as that from wireless RF radiation transmitting antennas?

In recent years, publicity, speculation, and concern over claims of possible health effects due to RF emissions from hand-held wireless telephones prompted various research programs to investigate whether there is any risk to users of these devices There is no scientific evidence to date that proves that wireless phone usage can lead to cancer or a variety of other health effects. However, studies are ongoing and key government agencies, such as the Food and Drug Administration (FDA) continue to monitor the results of the latest scientific research on these topics. The World Health Organization has also established an ongoing program to monitor research in this area and make recommendations related to the safety of mobile phones.

The FDA, which has primary jurisdiction for investigating mobile phone safety, has stated that it cannot rule out the possibility of risk. Further, it has stated that, while there is no proof that cellular telephones can be harmful, concerned individuals can take various precautionary actions, including limiting conversations on hand-held cellular telephones and making greater use of telephones with hands-free kits where there is a greater separation distance between the user and the radiating antenna.

The Government Accounting Office (GAO) prepared a report of its investigation into safety concerns related to mobile phones. The report concluded that further research is needed to confirm whether mobile phones are completely safe for the user and the report recommended that the FDA take the lead in monitoring the latest research results.

The FCC's exposure guidelines specify limits for human exposure to RF emissions from hand-held mobile phones in terms of Specific Absorption Rate (SAR), a measure of the rate of absorption of RF energy by the body. The safe limit for a mobile phone user is SAR of 1.6 watts per kg (1.6 W/kg), averaged over one gram of tissue, and compliance with this limit must be demonstrated before FCC approval is granted for marketing of a phone in the United States.

The severity of RF radiation overexposure is a function of channels, frequency, power, proximity to the RF source and duration of the exposure. All of these factors are substantially greater when the RF source is a wireless antenna or group of collocated antennas. The power, for example, of a wireless antenna is hundreds of times greater than that of a cell phone. Accordingly, the risk posed by an RF radiation transmitting antenna is significant.

### What are wireless telecommunications base stations?

Fixed antennas used for wireless telecommunications are referred to as cellular base stations, cell stations, PCS (Personal Communications Service) stations or telephone transmission towers. These base stations consist of antennas and electronic equipment. Because the antennas need to be high in the air, they are often located on towers, poles, water tanks, or rooftops. Typical heights for freestanding base station towers are 50-200 feet.

Some base stations use antennas that look like poles, 10 to 15 feet in length, that are referred to as omni-directional antennas. These types of antennas are usually found in rural areas. In urban and suburban areas, wireless providers now more commonly use panel or sector antennas for their base stations. These antennas consist of rectangular panels, about 1 by 4 feet in dimension. The antennas are usually arranged in groups of three antennas each. One antenna in each group is used to transmit signals to wireless phones, and the other two antennas in each group are used to receive signals from wireless phones.

At any base station site, the amount of RF radiation produced depends on the number of radio channels (transmitters) per antenna and the power of each transmitter. Typically, 21 channels per antenna sector are available. For a typical cell site using sector antennas, each of the three transmitting antennas could be connected to up to 21 transmitters for a total of 63 transmitters.

### What do RF radiation transmitting antennas look like?

To see common examples of such antennas, visit Examples of Wireless Antennas.

Note, however, that wireless antennas can take several forms as a result of efforts to camouflage or disguise them as other objects. Additionally, some antennas may be hidden entirely within the structures of buildings. As a result, it may be difficult or impossible to identify the existence and specific location of all RF radiation hazard zones at some sites.

### If I am working near an RF transmitter and I know it, how long can I work near it and how close can I get?

The severity of a potential RF radiation exposure is dependent upon the power, channels, frequency, proximity to the RF emission source, type of antenna and the duration of the exposure. Without knowing all of these factors, it is impossible to safely and confidently work near an RF transmitter.

Only workers who satisfy the FCC’s requirements for qualified workers who are "fully aware" and "able to exercise control" should ever be allowed to enter areas where the RF radiation levels may exceed the maximum permissible exposure (MPE) limit for General Population/Uncontrolled exposure.

All the various tradespeople who might visit a rooftop RF environment – HVAC, elevator repair, window washer, electricians, roofers, painters, maintenance workers – cannot possibly be classified as "fully aware" and "able to exercise control".

## RF CHECK Solution

### Does the Federal Communications Commission (FCC) routinely monitor RF radiation from wireless antennas?

The FCC does not have the resources or the personnel to routinely monitor the emissions for all the thousands of transmitters that are subject to FCC jurisdiction. However, the FCC does have measurement instrumentation for evaluating RF radiation levels in areas that may be accessible to the public or to workers. If there is evidence for potential non-compliance with FCC exposure guidelines for a FCC-regulated facility, staff from the FCC's Office of Engineering and Technology or the FCC Enforcement Bureau can conduct an investigation, and, if appropriate, perform actual measurements. This Guide can be accessed at: http://www.fcc.gov/oet/rfsafety. Potential exposure problems should be brought to the FCC's attention by contacting the FCC RF Safety Program by e-mail: rfsafety@fcc.gov.

### Are current safety practices effective in protecting all workers?

Cell phone use has become an integral part of everyday life in this nation. The wireless telecommunications industry enjoys tremendous popularity, if not dependence upon it. Consumer demand continues to grow, unabated, for existing and new technologies, products and services.

The rapid growth of the industry has been astronomical. In 1998, there were 60.8 million wireless subscribers in the United States. Now there are more than 277 million subscribers, representing nearly 89% of the total U.S. population. In order to supply consumers with its widely popular products and services, the wireless industry has expanded its wireless networks, resulting in a dramatic increase of the number of deployed wireless network components, such as base stations and antennas. For example, in 1996, there were fewer than 23,000 wireless antenna sites in the United States. Today, the wireless industry’s advocacy group, CTIA, states that more than 245,000 cell sites exist throughout the country, many of which host multiple wireless antennas, pulling the total estimated number of cellular antennas up to well over 600,000.

These wireless transmission sites come with an environmental, health and safety hazard: RF radiation. The ability to ensure workers’ health and safety has become far more difficult since the time the Federal Communications Commission (FCC) established RF radiation human exposure limits and standards. Strategies and methodologies to protect workers have been outstripped and rendered obsolete by the astonishing, rapid proliferation of wireless networks. RF radiation transmitting antennas are omnipresent – no longer limited to isolated, remote towers. They are located on rooftops, sides of buildings, utility poles, flag poles, lighting standards, camouflaged and concealed entirely within buildings. Workers that are compelled to work in proximity to RF radiation transmitters are no longer limited to the wireless industry’s RF trained technicians with protective gear and equipment. Rather, roofers, electricians, carpenters, maintenance personnel, HVAC technicians, painters, first-responders and a multitude of other trades are routinely required to work near RF radiation transmitting antennas despite being denied RF safety training and even information relative to the existence and location of RF radiation hazards.

Workers are routinely exposed to excessive levels of RF radiation because no effective, comprehensive RF radiation safety system is currently in operation. A number of practical challenges render it impossible for wireless service providers or the wireless industry alone to ensure the protection of all workers and the welfare of their families. These practical challenges include the following:

1. The impossibility or impracticality of service providers to have continuous (24/7) knowledge and control of all activities at antenna sites;
2. Mandated use of “stealth” antennas that prevent workers from identifying the existence and location of RF radiation hazards at work sites;
3. Mandated collocation of RF radiation transmitting antennas that results in increased cumulative RF radiation emissions, more RF radiation hazards at a site and coordinate power-downs among multiple service providers more complex;
4. Locks, fences and restricted access may protect service providers’ and property owners’ physical assets from theft and vandalism, but they do not protect workers who are compelled to enter restricted areas to fulfill their job responsibilities;
5. Signage is often missing, mislabeled, unintelligible and outdated (particularly in an industry where mergers and acquisitions are common);
6. The practice of outsourcing work to third-parties is an increasingly common means to cut operational costs;
7. Third-party workers are generally not provided RF radiation training and are, therefore, largely uninformed of RF radiation emissions and the risks they pose;
8. Pole attachments (potentially the fastest and least expensive method of expanding networks) are pursued in the hurry-up world of fierce competition that does not always include careful engineering, permission to attach facilities, code compliant construction and maintenance;
9. No national uniform standards exist for mapping and facility documentation;
10. Thorough, ongoing inspections and audits are not consistently and routinely undertaken;
11. No current solution includes the participation of all required stakeholders (i.e., commercial service providers, property owners hosting antenna sites, employers, local governments and the workers, themselves); and
12. Current RF radiation health and safety methodologies lack independence, transparency and validation.
This list is merely illustrative. Numerous other practical considerations giving rise to this national worker safety issue certainly exist.

### Can a single service provider or the wireless industry, as a whole, solve this national RF radiation health and safety problem?

The only viable solution must be a comprehensive, open and continuously collaborative RF safety program that involves all participants (service providers, building owners, property managers, city/county/state governments, contractors and workers, themselves).

### Why is the RF CHECK RF radiation safety solution needed?

The only viable solution must be administered by a neutral, objective private party. Governmental, regulatory resources have been proven to be inadequate. It is not a question of more regulations or enforcement resources, but the need to create the ability to comply with existing FCC and OSHA standards. The solution demands open, continuous collaboration among all interested parties (i.e., Service Providers, city/county/state/federal governments, building owners, property managers, contractors and workers).

RF CHECK will serve as a neutral, third-party administrator of its comprehensive RF safety system to facilitate the requisite participation of all interested parties. This neutrality ensures transparency, objectivity and validation of the safety solution – free from actual, potential and perceived conflicts of interest.

### What is the RF CHECK RF radiation safety solution?

At its most fundamental level, the RF CHECK system is a living database consisting of 600,000 of governmental and commercial wireless antennas and their unique characteristics. The Company's proprietary system contains information which allows the wireless industry to meet all local, federal and international RF radiation compliance regulations and to protect all workers from excessive RF radiation exposure.

The RF CHECK system contains cost saving engineering tools, digital images of each antenna site, site specific contact information and the ability to deliver Site Specific Safety Plans including RF “Maps of the Invisible™” to all individuals working at wireless sites throughout United States and the world.

The proprietary system also includes an RF radiation training and certification program, as well as a method for powering-down wireless antenna sites for worker protection.

RF CHECK has multiple user interfaces for the wireless service providers, the FCC, OSHA, state and local municipalities, utility companies, antenna site owners, property management companies, industry contractors, and numerous other entities.

### Who benefits from the RF CHECK RF radiation safety solution?

The RF CHECK system provides a comprehensive RF radiation safety and compliance program for all individuals and entities affected by RF radiation emissions from wireless antennas located throughout the United States and the world.

Fundamentally, all workers will be protected and the welfare of their families preserved.

All wireless industry stakeholders will realize the greatest socially responsible achievement (ensuring the health and safety of individuals) through a scalable, economic solution.

The RF CHECK system can benefit all participants in the wireless communications industry by helping protect their financial assets, reduce operational expenses, preserve public image, standardize and ease the approval process of new sites, promote greater site worker safety, and provide immediate regulatory compliance with FCC-OSHA regulations.

RF CHECK will serve as a neutral, third-party administrator of the comprehensive RF radiation health and safety solution to ensure expertise, objectivity, accurate monitoring of the wireless industry’s compliance activities and to eliminate actual and perceived conflicts of interest that otherwise would exist.
