are thus not the subject of the safety questions discussed in this document.
3.What kinds of phones are the subject of this update?
The term ‘wireless phone’ refers here to handheld wireless phones with
RF exposures far below the FCC safety limits.
4.What are the results of the research done already?
The research done thus far has produced conflicting results, and many studies have suffered from flaws in their research methods. Animal experiments investigating the effects of radiofrequency energy (RF) exposures characteristic of wireless phones have yielded conflicting results that often cannot be repeated in other laboratories. A few animal studies, however, have suggested that low levels of RF could accelerate the development of cancer in laboratory animals. However, many of the studies that showed increased tumor development used animals that had been genetically engineered or treated with cancer causing chemicals so as to be predisposed to develop cancer in the absence of RF exposure. Other studies exposed the animals to RF for
up to 22 hours per day. These conditions are not similar to the
