NTP May Test Cell Phones

Article excerpt

At its 30 June 2000 meeting, the Executive Committee of the National Toxicology Program (NTP) approved a recommendation for the NTP to study radio frequency radiation emissions from wireless communication devices, which include cellular phones. The NTP is currently evaluating the need, feasibility, and scope of a possible testing program.

The recommendation came from the Food and Drug Administration, which regulates electronic products that emit radiation. The administration noted in its nomination that in the United States alone over 80 million people currently use portable communication devices, with about 25,000 new users daily.

Cell phones use low-level microwave radiation to communicate between the caller and a base station. If tissues are exposed to strong enough microwave fields, the rise in tissue temperature can cause well-documented thermal effects such as cataracts, deep-tissue burns, and heat stroke. Cell phones are currently required to meet exposure guidelines established by the Federal Communications Commission to protect against acute injury from thermal effects. …
