Radiation: Should I be concerned?
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Dr Fred Kavalier answers your health question:
Bluetooth earpieces are low-power microwave transmitters that communicate with mobile phones. When you speak into the Bluetooth microphone, your voice is transmitted to the mobile phone and the earpiece receives the sound from your mobile conversation. The frequency of the radio waves is in the same range as the frequency used in microwave ovens. So, I suppose, in a sense a Bluetooth earpiece is a bit like a tiny microwave oven. But Bluetooth earpieces use about one-millionth of the power of microwave ovens, and only a tiny proportion of this is absorbed by the body. Scientific experiments have not been able to detect any increase in body temperature from Bluetooth earpieces. Even compared to holding a hand-held mobile phone next to your ear, Bluetooth earpieces are certainly much less of a radiation risk. If you are concerned, the answer is to use an earpiece that is connected to the phone by a wire. This avoids any significant radiation exposure.
