I wonder about the effects of the Bluetooth Ear pieces that you see a lot of people wearing for talking on the phone and listening to music. I have read that bluetooth is a low microwave radiation. Will long-term use cause damage to the ear drum leading to diminished hearing or even deafness?
Also what effect do these video glasses that people use for playing games have on the eyes? Maybe in the future there will be a lot of deaf and blind people from using these devices.
this is the closest I can quickly find for the plastic head radiation test.
SAR testing uses standardized models of the human head and body that are filled with liquids that simulate the RF absorption characteristics of different human tissues. In order to determine compliance, each cell phone is tested while operating at its highest power level in all the frequency bands in which it operates, and in various specific positions against the dummy head and body, to simulate the way different users’ typically hold a cell phone, including to each side of the head. To test cell phones for SAR compliance, the phone is precisely placed in various common positions next to the head and body, and a robotic probe takes a series of measurements of the electric field at specific pinpoint locations in a very precise, grid-like pattern within the dummy head and torso. All data for each phone placement are submitted as a part of the equipment approval test report for final authorization. However, only the highest SAR values for each frequency band are included in the final authorization to demonstrate compliance with the FCC’s RF guidelines.

Don't know but I wonder about it as well!
Beautiful picture!

Does your friend have Internet? If so, he could get a Google Voice number, which is free.
Thank you. I will encourage him to do that.
