National Toxicology Program researchers released preliminary data in May that showed small increases in tumors in male rats exposed to cellphone radiation. Industry and federal officials have largely dismissed those fears, saying the radiation exposure is minimal and that the devices are safe. “I don’t think it’s clear that there are health risks, but it’s also not clear that there are no health risks,” said Leeka Kheifets, an epidemiology professor at UCLA’s Fielding School of Public Health who has studied the health effects of cellphone use. As wireless companies prepare to launch the next generation of service, there are new questions about the possible health risks from radiation emitted by cellphones and the transmitters that carry the signals. The FCC also regulates the exposures from base stations transmitting wireless signals.
