Scientists have found that one is dangerous mobile phone radiation and what are the effects of the impact. What are the findings and opinions of experts and what is wrong, the media says “Газета.Ru”.
The media once again reported that mobile phone radiation causes cancer, not only the brain but also other organs. The source was the publication of a studyconducted in the framework of the National program of toxicology (NTP) project, launched in 1978 to coordinate Toxicological research of the Ministry of health and social services.
Preliminary results were received in February 2018, however, they demanded a review.
Mobile phones emit non-ionizing electromagnetic radiation, which some scientists are already not the first year trying to associate with cancer and other diseases. The hypothetical harmful effects of mobile phone radiation on human health is causing a fierce debate is already not the first year. However, most studies do not show an unambiguous link between radiation and cancer in humans. To clarify the situation, the Management on sanitary inspection behind quality of foodstuff and medicines has commissioned researchers to carry out in the framework of the National program of toxicology research on the effects of radiation on living organisms.
In the experiment, the scientists worked on mice and rats using radio-frequency radiation, such as in 2G and 3G networks. The minimum level of exposure in animals was the maximum permissible level of acupressure today’s mobile phones, and the maximum exceeded it four times: from 1.5 to 6 watts per kilogram of body weight for rats and from 2.5 to 10 watts per kilogram for mice.
Rats were exposed to radiation in the womb, mice at 5-6 weeks of age. Irradiation was continued throughout their lives. The RF exposure was intermittent generator turn on and off every 10 minutes for 9 hours a day.
The results of these experiments it was found that the male rats developed cancer of the heart. Less frequently they have a brain tumor and adrenal glands. For female rats and male and female mice, the results were mixed.
“We believe that the link between radiofrequency radiation and cancer in male rats is real,” says lead study author John Bucher.
“The strength of our work is that we were able to control how much radiation will get animals, says toxicologist Michael Wide. — In the study of human exposure is impossible.”
Despite the formation of cancer tumors, irradiated male rats lived longer than the control group. The researchers attribute this decline to chronic kidney problems that often cause of death in older rats.
Do people worry for their health in light of new evidence?
First, the study considers both 2G and 3G networks used less often. More modern and current technology, it has not been studied. Second, animals were exposed to radiation in much larger quantities than is usual with people. Thirdly, the animals were exposed whole body, while people in conversation most often holding the phone to my head. Fourth, scientists have not identified-dependence was — the Association of tumor development with doses of irradiation.
“To compare the effects in experiments and the effect inflicted on a person using the mobile phone directly is impossible,” — said Bucher.
“Animal studies such as this contribute to the discussions on the topic of radiation. However, we must understand that the study has not been studied the safety the use of mobile telephones in people, so we cannot draw conclusions about the risks, says Jeffrey Shuren, Director of the Center for devices and radiological health impact of Management on sanitary inspection behind quality of foodstuff and medicines of the USA. The totality of available scientific evidence still does not indicate adverse effects to human health under the current conditions of the radio emission. We believe that existing safety limits for the use of mobile phones remain acceptable to protect the health of the population.”
The specialists of the NTP, meanwhile, plan to further study the impact of the newer technologies — they already have developed methods that will allow to conduct experiments for weeks or months, not years.
In addition, the researchers expect to identify biomarkers that indicate early exposure to RF radiation on the organism of rodents, changes in heart rate or molecular changes, heralding cancer.
“If scientists can better understand what biological changes occur in the body of animals, they will know better what to pay attention in humans,” they say.
