Answer to Question #6064 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
My wife (who's seven months pregnant), our two-year-old child, and I
are considering relocating. The property of interest is approximately
1.5 miles from the largest AM radio transmission tower (100,000-watt
signal tower) in the country. Please comment on the health
effects of these towers. How does the radiation from AM towers differ
from FM towers and cell phone towers?
A
Radiofrequency (RF) radiation is nonionizing and very different from ionizing radiation such as x rays and gamma rays, which can be carcinogenic. The primary mode of interaction for RF radiation is thermal and it is therefore inherently safe. There is no evidence that RF radiation is hazardous when regulatory standards are met. There has been so much research conducted on RF radiation, the strong consensus of government, industry, and academia is that the levels associated with these wireless products is safe. At a distance of 1.5 miles from this transmission tower, you are well beyond any level of concern. Your pregnant wife, your child, and you have nothing to be afraid of, though I would not hesitate to request information about any surveys done on this particular tower. Since they have made a claim of being the most powerful tower in the country, this most likely has resulted in some safety surveys.
I am attaching several very useful websites with much more information than I can provide.
Cellular telephones, radio, AM, FM, or television are all in the RF
portion of the electromagnetic spectrum. The first URL, an Australian
website, has some nice information. The levels of RF exposure are in
the microwatt per cm2 range. FM transmission towers are slightly more
restrictive in terms of power densities than AM towers. Regardless, the
exposure levels humans are exposed to are well below regulatory and
industry standards regardless of the tower type.
