To whom it may concern,

I am writing to express my opinion and concern on the possible health effects of exposure to radiofrequency radiation from wireless transmitters and transmission antennae (e.g., AM and FM radio, and TV transmission).

The level (intensity) of radiation from a transmitter that one would be exposed to is very low, mainly because of the distance from the transmitter. The level is generally considered to be harmless. Most research in this area deals with radiation of much higher levels. However, some recent studies have suggested that exposure to radiation similar in intensity to those from cellular phone base station transmitters is not completely safe. A list of biological studies on low-level effects (within the levels of exposure less than 200 ft from a transmitter) is attached with this letter. Many of these studies reported effects, e.g., brain cell damage, DNA damage, learning deficit., that could potentially lead to serious adverse health effects.

Furthermore, when considering the health effect of radiation from wireless transmitters, one has to consider the effect of long-term exposure. People who live close to transmitters are constantly being exposed to the radiation for months or years. Even though the level is low, it would matter if the effects of radiofrequency radiation turn out to be cumulative (i.e., add up over time). Small doses cumulate over a long period of time will eventually lead to harmful effects. Most of the studies in the attached list only investigated short term exposure effects and little is known about long-term exposure.

Therefore, exposure of the general public to radiofrequency radiation from wireless transmitters should be limited to a minimal. Broadcast antennae should be located at a significant distance from populated areas, schools, day care centers, and hospitals.
