A study commissioned by the United States Food and Drug Administration (USFDA) has concluded that there is a link between high levels of radio frequency radiation (RFR) - like that used in 2G and 3G cellphones - and cancerous heart tumors in male rats, which were exposed to high-level RFR.
According to NTP, the findings do not directly apply to humans.
It took 10 years for NTP to complete the most comprehensive study on RFR to date, and researchers surmise that the results of their investigation could serve as a guide in the research and development of new technologies.
In should also be noted that the types of RFR used for Wi-Fi or 5G networks were not included in this investigation. "The exposures used in the studies can not be compared directly to the exposure that humans experience when using a cell phone", Bucher said in a news release.More news: How To Rock An Oversized Shirt Like Deepika Padukone
"Animal studies like this one contribute to our discussions on this topic, but we must remember the study was not created to test the safety of cell phone use in humans, so we can not draw conclusions about the risks of cell phone use from it".
"The exposures used in the studies can not be compared directly to the exposure that humans experience when using a cell phone". On long calls, he said, he tried to use earbuds or find other ways "of increasing the distance" between the cellphone and his body, in keeping with advice issued to consumers about how to lower their exposure.
"We studied the effects of almost lifetime exposures to two different types, or modulations, of RFR (GSM and CDMA) used in cellular telephone networks in the United States in male and female rats and mice to identify potential toxicity or cancer-related hazards". The highest exposure level in the studies was four times higher than the maximum power level permitted. A major study is hoping to answer some of those questions.
The study involved radio frequencies long out of routine use.
For the study, the animals were housed in special chambers so the researchers could control how much radiation they received. The animals were exposed to a total of 9 hours of radiation per day, in 10-minutes sessions. For the rats, the exposures started before birth and continued until they were about two years old. RFR levels ranged from 1.5-6 watts per kilogram in rats, and 2.5-10 watts per kilogram in mice.More news: Alexandre Lacazette Salvages Arsenal's Unbeaten Run, Slows Liverpool's Title Charge
"5G is an emerging technology that hasn't really been defined yet. From what we now understand, it likely differs dramatically from what we studied", said Michael Wyde, lead toxicologist on the studies. NTP will provide the results of these studies to FDA and the Federal Communications Commission, who will review the information as they continue to monitor new research on the potential effects of RFR.
"Animal studies like this one contribute to our discussions on this topic, but we must remember the study was not created to test the safety of cellphone use in humans, so we can not draw conclusions about the risks of cellphone use from it", Dr. Jeffrey Shuren, director of the Food and Drug Administration's Center for Devices and Radiological Health, who was not involved with the study, said in a statement.
