High exposure to radiofrequency radiation — the radiation known as
RFR and emitted from your cell phone — causes a rare cancer in male
rats, according to draft conclusions released by the National Institutes
of Health on Friday.
The two technical reports,
one on mice and the other on rats, released by the NIH’s National
Toxicology Program (NTP) show the exposure to the high levels of
radiation resulted in tumors in the tissues surrounding nerves in the
heart of male rats.
Both male and female rats that were exposed to high levels of RFR
showed increased patterns of damage to their heart tissue, according to
the researchers.
“The levels and duration of exposure to RFR were much greater than
what people experience with even the highest level of cell phone use,
and exposed the rodents’ whole bodies. So, these findings should not be
directly extrapolated to human cell phone usage,” said NTP senior
scientist Dr. John Bucher in a written statement. “We note, however,
that the tumors we saw in these studies are similar to tumors previously
reported in some studies of frequent cell phone users.”
Bucher said these studies “provide the most comprehensive assessment,
to date, of health effects in rats and mice from exposure to RFR.”
Researchers said that newborn rats and their mothers had lower body
weights, especially when exposed to high levels of RFR during pregnancy
and lactation. However, those animals eventually grew to normal size.
The U.S. Food and Drug Administration and the Federal Communications
Commission jointly are responsible for regulations pertaining to
wireless communication devices.
NTP will hold an external expert review of its complete findings on these studies in late March.
