On September 16, Apple's latest mobile phone iPhone7 was officially launched in mainland China. The biggest feature of the iPhone7 is the abandonment of the 3.5mm headphone jack that has existed for nearly 140 years, leaving only one Lighting interface and enabling the AirPods wireless headset design. Techradar reviewers have said that the death of the 3.5mm headphone jack is a good thing, because Lighting and Bluetooth are mature enough to transmit audio signals. However, there are public health experts in the United States who point out that this wireless headset has radiation problems that can damage the brain's vascular barrier. In this regard, Professor Normand La Perrier of the University Health Network Medical Center in Canada said that even with only a small amount of radiation, the impact on the human body is relatively large. He suggested not to listen to songs and make phone calls with Bluetooth headsets for a long time, so that we seem to have returned to the debate that mobile phones were harmful to health.
Radiation is harmful, transmitting waves to the ear can weaken the cerebral vascular barrier
According to the British "Daily Mail" report, Apple's new iPhhone7 uses a wireless Bluetooth headset called AirPods, which caused public public curiosity. The Apple AirPods are smooth and waterproof, which avoids the problem of tangling the headphones. The headset is powered by Bluetooth technology and delivers low-intensity waves to the ear. However, public health experts point out that such headphones can endanger human health.

Studies have shown that time-out transmitting radio waves into the ear can weaken the vascular barrier of the brain. The cerebral vascular barrier is an important organ that prevents chemical toxins from entering the body. Dr. Joel Moskowitz, a professor at the University of California at Berkeley Public Health, said that bringing microwave transmission equipment closer to the brain is undoubtedly a self-immolation. "This is equivalent to placing a microwave emitter next to the brain," he said.
According to the report, the exact frequency of AirPod Bluetooth transmission has not been announced yet. Apple engineers and marketing directors said that Apple's Bluetooth technology, its radio transmission strictly adheres to the Federal Communications Commission (FCC) guidelines, and Bluetooth transmits much less radiation than microwave ovens.
In this regard, Dr. Moskowitz countered that more than 200 experts in the field of electromagnetics have said that the US Federal Communications Commission guidelines are not enough to protect human health.
He said, "Although we don't know how long the long-term hazards of using Bluetooth devices are, why should we put the microwave transmitters in our ears so close to the brain? Are we not using other ways to use the phone more safely?" Therefore, he suggested users Use a wired headset or turn on the handsfree and try not to use a wireless headset.
