According to the CDC, there is no conclusive evidence that cellphone radiation does or does not cause health problems. Bluetooth earpieces produce less than one one-hundredth of the radiation produced by cellphones, reports CNN. The CDC recommends that people who are concerned about radiation use a hands-free headset.
Both cell phones and Bluetooth accessories produce radiofrequency radiation, which is different that other radiation types. The International Agency for Research on Cancer classifies radiofrequency radiation as a possible cancer-causing agent.
The World Health Organization investigates possible health problems caused by cellphone radiation. WHO scientists research the effects of cell phone radiation on human eyes, sleep, tumors, memory and headaches.
