Answer to Question #459 Submitted to "Ask the Experts"Category: Microwaves, Radar, and Radiofrequency — Microwaves and Radiofrequency The following question was answered by an expert in the appropriate field: Q
I'm thinking of buying a small portion of land near (30m) some big antennae for airplanes transmissions (high place). Is there any health danger or any risk regarding the closeness of these antennae? Is there any cause-effect proven due to these radiations? Where can I read about these kinds of problems on the Internet? Thanks.
A
In the United States, the radiation level outside the boundary fence is required to be well below any known exposure hazard level (See Title 47--Telecommunication at the GPO Access website, then select section 1.1310).
While it is possible to calculate the approximate RF exposure hazard given enough information about the antenna, frequency, and power levels, the only way to know the level of a potential RF exposure hazard (even in the United States) is to have a qualified RF engineer survey the property with appropriate meters for the frequencies and power levels being used at the antenna site and then evaluate the results for acceptable risk. Note the use of the phrase "acceptable risk." For general information on effects and potential hazards associated with antennae emitting radiofrequency electromagnetic fields, you may wish to consult Federal Communications Commission publication OET Bulletin No. 56, Questions and Answers about the Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields, available at the FCC website.
