Studies offer no clear answers on safety of cellphone use
WASHINGTON — Two government studies that bombarded rats and mice with cellphone radiation found a weak link to some heart tumors, but scientists and federal regulators say don’t worry — it is still safe to use your device.
Previous studies of cellphone users had found little reason for concern, but the newest research took a closer look at the effects of super-high doses in animals to address some lingering questions that could not be tested on humans.
The rat study released Friday found a small increase in an unusual type of heart tumour in male rats but no other significant problems in females or in a separate study of mice. In particular, scientists could not find hard evidence for concern about brain tumors.
The lead author of the research, John Bucher of the National Institute of Environmental Health Sciences, is not changing his cellphone use or advising his family to.
