Do Bluetooth devices increase the risk of brain cancer?
With the industrialization of society and the continuous development of high technology, the number of electromagnetic radiation sources and the diversified equipment has been supplied on an unprecedented large scale; then is battery radiation safe?
According to data from the National Institute of Environmental Health Sciences, battery radiation is released as a kind of energy that cannot be felt or seen and can exist in nature, such as sunlight. It can also be emitted from synthetic equipment objects, such as X-ray irradiation equipment, radioactive waste disposal fields, and non-ionizing battery radiation equipment. The latter refers to mobile phones, computers, Internet, energy, smart meters, microwave ovens, high-voltage power lines, MRI scanning machines, Bluetooth devices, and so on.
In recent years, wireless Bluetooth headsets have become very popular, and a recent consumer survey shows that more than half of Americans buy various Bluetooth devices every year. In general, Bluetooth devices may generate more than 100 times the battery radiation energy of ordinary mobile phones, and weak battery radiation energy has no effect on the body, but long-term exposure to high-energy battery radiation can cause health risks. For example, during pregnancy, it may cause more than three times the chance of miscarriage; it may also cause children to have attention deficit hyperactivity disorder. In addition, some studies believe that exposure to mobile phones and Bluetooth devices is related to brain tumors and tinnitus.
However, the U.S. Food and Drug Administration believes that although the use of mobile phones has increased at an unprecedented rate (mobile phones appeared in 1973 and only began to become popular after 1990), the incidence of brain cancer has remained the same; Bluetooth may not increase the risk of brain cancer.
