The radiation level of the Xiaomi Smart Band is very low. According to tests conducted by experts from organizations like the World Health Organization and IEEE, the radiation output power of Bluetooth devices is only 1 milliwatt, which is one-millionth of the power used by microwave ovens and one-thousandth of the power used by mobile phones. Furthermore, only a small portion of this output is absorbed by the human body.
Bluetooth radiation is significantly lower compared to directly using a mobile phone for calls or using traditional wired headphones. It is considered green and safe, even for children and pregnant women.
In summary, Bluetooth radiation is only a fraction of that from mobile phones and is almost negligible, making it a radiation-safe product and a more environmentally friendly way to use mobile devices.
