The California Department of Public Health Wednesday released a new set of guidelines concerning the use of cellphones and radiation risk.
Some studies have suggested that long-term use could be linked to brain or salivary gland cancer, lower sperm count, and headaches, the department said. And a study from Kaiser Permanente published this week in Scientific Reports found an association between exposure to the type of radiation emitted by cellphones and other sources and a higher rate of miscarriage. But the department was cautious in its framing of the potential harm:
"These studies do not establish the link definitely, however, and scientists disagree about whether cellphones cause these health problems and how great the risks might be," the guidelines state. "This document is intended to provide guidance for those people who want to reduce their own and their families’ exposures to RF [radio frequency] energy from cellphones, despite this uncertainty."
The creation of the guidelines was spurred by the exploding use of cell phones in recent years, said CDPH Director Dr. Karen Smith.
"We're finding that many more children are using cellphones and they're using them at earlier ages," Smith said.
