The study focused on high levels of radio-frequency radiation
A study commissioned by the US Food and Drug Administration (USFDA) concluded that Existence of a link between high levels of radio-frequency (RFR) radiation – such as those used in 2G and 3G cell phones – and cancerous cardiac tumors in male rats, which have been exposed to high-level RFRs .
According to the latest reports of the study, there is clear evidence that male rats exposed to high levels of radio frequency radiation developed these tumors
There was also evidence of tumors in the brain and the adrenal gland of exposed male rats. For female rats and male and female mice, the evidence was ambiguous as to whether the observed cancers were badociated with RFR exposure.
from the US National Institutes of Health's Environmental Health Sciences was commissioned to conduct the effects study of the RFR.
In the NTP studies, the report states that the exposure was far greater than what happens with the average length of the cell phone. John Bucher, NTP's senior scientist, said, "The exposures used in the studies can not be directly compared to the exposure that humans experience when they use a cell phone. In our studies, rats and mice received radiofrequency radiation all over their body. In contrast, people are primarily exposed in specific local tissues close to where they hold the phone. "
In addition," exposure levels and exposure times in our studies were higher than what people live. "
Lowest exposure. indicates that the level used for the study is equal to the current maximum permissible local tissue exposure for mobile phone users.This power level is rarely used with a typical mobile phone.
highest exposure in studies was four times higher than the maximum power level allowed.
"One of the strengths of our studies is that we were able to control exactly a lot of radio radiation received by animals – thing impossible when one studies the use of the human cell phone, which often relies on questionnaires, "said Michael Wyde, chief toxicologist of the study.
L & # 39, study has co Started at a time when 2G and 3G networks were the norm – they are still used for calls and sending SMS – and have not studied the types of RFRs used for Wi-Fi or Wi-Fi networks. 5G.
This further adds to the hypothesis that there is a link between mobile phone use and cancer. .
