Relay antennas and our smartphones continuously bomb us. These radiations caused by electromagnetic waves raise questions, but the real health risks are still unclear. However, researchers from the US have established a link between the emission of radio waves and the development of cancerous tumours in rats.
The United States National Toxicology Program (NTP) has finalized a study, the culmination of ten years of research. The research indicates that there is “clear evidence” that electromagnetic waves represent a health hazard.
However, the study demonstrated this link only in rats and not in humans. A first interim report had already been tabled in February of this year, mentioning that there was “some evidence,” but scientists have since hardened their diagnosis.
According to Bloomberg, John Bucher, a scientist at the NTP stated that “the shift from some evidence to clear evidence reflects increased confidence that cancer observed in male rats was associated with radio frequency exposure.”
Electromagnetic Waves Generated By Smartphones Linked To Tumor Development In Rats
During their research, scientists exposed rodents to electromagnetic waves radiations more potent than usual and more prolonged than what humans endure during a phone conversation on their smartphones.
Although proven in rats, these results would not apply to humans, eventually. According to the Food and Drug Administration (FDA), the radiation levels used in this study are by far exceeding the normal levels when people use their phones. In addition to that, some inexplicable observations do not allow clear links to be established. Accordingly, the exposed rats lived longer than their unexposed peers, while only the males developed heart tumors and the risk of damage did not increase with the radiation dose.
In short, the scientific community does not agree on these results. While a Berkeley professor says that these results are “to be taken very seriously,” the director of an FDA department says that “the study was not designed to test the safety of cell phone use in humans,” so it would not allow conclusions to be drawn about the health risks of smartphone use.
