Radiaiton in cars

The radiation issues in hybrid cars are turning to be a real thing. Reports from around the world about measurements of high radiation levels are coming out.

All "regular" cars radiate from low frequency electromagnetic sources like the alternator, car's electric system, and the layers. In hybrid and electric cars you have to add also the electric motors, the electric batteries, and the power conductor from the batteries to the motors.

In some of the cars there are also some high frequency radiation sources like the car's Bluetooth system, car tracking systems, the wireless key, Wi-Fi and mobile communication systems, and of course the passengers and driver mobile phones.

Using your mobile phone inside your car ( a close metallic object), other than taking the driver's mind off the road, results with you espousing yourself to high levels of radiation.

Below is a like to an article that summaries measurements of several cars, both hybrid and "regular". The article is in French but you can get some of the info from the pictures or you can translate it.
