PUT DOWN YOUR PHONE: Comprehensive Study Finds High Cell Phone Use Causes Heart Tumors In Rats
Two U.S. government agencies are giving conflicting interpretations of a safety study on cellphone radiation: One says it causes cancer in rats.
That is sure to ignite more controversy among the people who believe cellphones can cause brain tumors and other illnesses based on the radiation they emit.
"The exposures used in our studies are not directly comparable to the exposures that humans typically experience when using a cellphone", the National Toxicology Program's John Bucher told reporters.
The FDA disagreed. "The current safety limits for cell phone radiofrequency energy exposure remain acceptable for protecting the public health", said Shuren, the Food and Drug Administration official.
The lowest exposure level used for the study was equal to the maximum local tissue exposure now allowed for cellphone users, the report states.
NTP senior scientist John Bucher said, "The exposures used in the studies can not be compared directly to the exposure that humans experience when using a cellphone".
Yes, cell phone radiation was linked to cancer in a new study, according to BuzzFeed News, but before you freak out, you should know that even the authors of the study are saying it's nothing to worry about. They lived in a cage, imitating the work of the mobile phone antennas, and some of them began to be the influence of radio waves is still in the womb, while others were in cages in adulthood. If the results of this study still makes you feel a little concerned about putting your smartphone to your ear, you can always opt to use earbuds to make your calls instead.
Some females and some mice developed tumors, but it was mainly male rats exposed to the highest levels of radiation that developed life-threatening cancers.
Researchers found that upon exposure to high levels of RFR, there was "clear evidence" of tumors in the hearts of male mice, "some evidence" of tumors in the brains of male mice, and "some evidence" of tumors in the adrenal glands of male mice.
Some scientists have warned that 5G - which uses milimeter waves, rather than the microwaves that were the basis of previous generations - may in fact be more unsafe, but its far too soon to tell for sure. No malignant gliomas developed in the control group.
Since the exposure levels and durations in the studies were greater than what people experience, "we agree that these findings should not be applied to human cell phone usage", the FDA said on Thursday. For comparison, fourth generation (4G) and fifth generation (5G) phones employ much higher frequencies, which are "far less successful at penetrating the bodies of humans and rats", the New York Times reports.
The NTP researchers are planning future studies on the effects of newer technologies, and these studies will use different methods so that they will be completed in weeks to months, rather than years.
But the results of the study do need proper context.
'The US IEEE-FCC human safety guidelines for wireless radiation which only protect against thermal heating or burning were scientifically false decades ago, ' said Dr Paul Heroux, a McGill University physicist and toxicologist.
For the study that was just released, the National Toxicology Program (NTP) collaborated with technical experts from the National Institute of Standards and Technology (Boulder, CO) and the Foundation for Research on Information Technologies in Society (Zurich, Switzerland).
At the exposure's lowest levels, it was equal to the maximum local tissue exposure allowed for mobile phone users, a level that rarely occurs during typical phone use.
