Cellphone Use Linked <br />to 'Some Evidence' of <br />Cancer, Says Study The U.S. Department of Health and <br />Human Services released the findings presented by the National <br />Toxicology Program on Thursday. The $30 million-study began <br />during the Clinton administration <br />and utilized 3,000 rodents. John Bucher, senior scientist at <br />the National Toxicology Program The exposure levels and <br />durations were greater than <br />what people usually encounter. Because of this, the results <br />can't "be compared directly to <br />the exposure that humans experience." The rats were exposed to <br />900 megahertz of radiation, which <br />is comparable to the second generation of cellphones <br />from the 1990s. Dr. Bucher, the senior scientist <br />at the toxicology agency, said the study encouraged him to find ways "of increasing the distance" between the cellphone and his body. Current cellphones exude much higher frequencies, which are less successful <br />at penetrating humans and rats. The toxicology agency <br />intends to enhance its program to be able to evaluate newer <br />technologies in weeks or <br />months, instead of years.
