Behavioral and Cognitive Effects of Microwave Exposure


This paper presents an overview of the recent behavioral literature concerning microwave exposure and discusses behavioral effects that have supported past exposure standards. Other effects, which are based on lower levels of exposure, are discussed as well, relative to setting exposure standards. The paper begins with a brief discussion of the ways in which behavioral end points are investigated in the laboratory, together with some of the methodological considerations pertinent to such studies when radio frequency (RF) exposure is involved. It has been pointed out by several sources that exposure to RF radiation can lead to changes in the behavior of humans and laboratory animals that can range from the perceptions of warmth and sound to lethal body temperatures.

The Impacts of Radiofrequency Radiation from Mobile Phone Antennas


This report addresses the evidence for the impact of radiofrequency radiation from mobile phone antennas on people’s health and well-being. Mobile phone antennas emit high frequency (radiofrequency) radiation that differs from naturally-occurring radiation in frequency and characteristics of the signal.


COMAR Technical Information Statement the IEEE exposure limits for radiofrequency and microwave energy


Excessive exposure to radiofrequency (RF) or microwave energy produced by radio transmitters, some industrial equipment, and other sources can be hazardous. For this reason, the IEEE has developed limits for human exposure to RF energy, and these limits have been widely influential around the world. The IEEE standard represents a consensus of scientific opinion about safe levels of exposure to RF energy, and its scientific rationale is consistent with conclusions of numerous expert groups and health agencies throughout the world. Nevertheless, laypeople often have questions about the adequacy of the standard or the process by which it was developed. This Technical Information Statement discusses the development and rationale for exposure limits for RF energy.


Neurological Effects of Radiofrequency Electromagnetic Radiation

Neurological Effects

The close proximity of a mobile telephone antenna to the user's head leads to the deposition of a relatively large amount of radiofrequency energy in the head. The relatively fixed position of the antenna to the head causes a repeated irradiation of a more or less fixed amount of body tissue. Exposure to RFR from mobile telephones is of a short-term, repeated nature at a relatively high intensity, whereas exposure to RFR emitted from cell masts is of long duration but at a very low intensity. The biological and health consequences of these exposure conditions need further understanding. 


ICNIRP: Guidelines for Limiting Exposure to Time-varying
Electric, Magnetic, and Electromagnetic Fields (up to 300 GHz)


The main objective of this publication is to establish guidelines for limiting EMF exposure that will provide protection against known adverse health effects. An adverse health effect causes detectable impairment of the health of the exposed individual or of his or her offspring; a biological effect, on the other hand, may or may not result in an adverse health effect. Studies on both direct and indirect effects of EMF are described; direct effects result from direct interaction of fields with the body, indirect effects involve interactions with an object at a different electric potential from the body. Results of laboratory and epidemiological studies, basic exposure criteria, and reference levels for practical hazard assessment are discussed, and the guidelines presented apply to occupational and public exposure.


OET 65: Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields


This revised OET Bulletin 65 has been prepared to provide assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to radiofrequency (RF) fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance.
