Cancer risk from cell phone radiation in rats but not extrapolated to humans



[ad_1]

A new study in laboratory rats has shown that mobile phone radiation exposure is linked to cancers of the brain, heart and adrenal glands. Rats, however, have been exposed to very high radiation, far more than what humans use when they use a cell phone.

In our studies, rats and mice received radiofrequency radiation all over their body. In contrast, people are mainly exposed in specific local tissues close to the phone. In addition, the levels of exposure and the duration of our studies was higher than that of people.

This study focused on 2G and 3G mobile phones, while current phones contain more than one antenna for Wi-Fi, GPS, 2G / 3G / 4G tapes, etc., explain the researchers. . Cancer Research UK said: "Even with the latest findings, there is still no convincing evidence that the cell phone causes cancer in humans." Despite the evidence and disparities between the situations and laboratory conditions, the results of the study are relevant to the modern world.

The results of the US National Toxicology Program (NTP) study (government program within the Ministry of Health and of Social Services) were published on November 1 of last week.Experimental rats were exposed to 900 megahertz radiation for an average of nine hours per day for two years .The lowest level of exposure was the maximum permissible exposure in accordance with federal regulations, while the highest exposure level was four times the maximum permissible exposure. results showed that two to three of the male rats had malignant glioma. This was comparable to the group of control rats that had no radiation and none of these control rats developed glioma or brain tumors. There was also "clear evidence" of cardiac tumors in exposed rats and "some evidence" linking radiation exposure to adrenal tumors. There was direct "equivocal" evidence of radiation-inducing tumors in female rats and mice.

However, according to the researchers, there was no increase in the incidence of gliomas or brain tumors with the increased use of cell phones. Dr. Jeffrey Shuren, head of radiological health at the FDA, also said that "these results should not be applied to the use of the human cell phone."

This new report is the last of many reports published by the NTP since May 2016 on the badociation of cell phone radiation and cancers. Not only the NTP researchers, this report was also a collaboration with external reviewers. The team is planning further studies to determine whether exposure to radiation in the chambers can cause DNA damage that can lead to cancer.

Experts cautioned that despite differences in laboratory exposure and real-life situations, people need to reduce their exposure to radiation. using headphones and holding phones further away from the body.
