I have looked at the unit a few times, to me looks like a Motorola 3 watt brain driving the communications, the connector on it looks like a db25 pin connector if I remember correctly. All one would have to do is disconnect the connector and the power lead. No juice to cellular transmitter = no radiation. Also these units have sheilded cables and such so most of the radiation is from the antenna except for minor leaks.
One last thing, those of you living in urban areas probably have less to worry about concrening radiation, here's why. Urban areas tend to have much better cell coverage (i.e. more towers) and more towers to help increase call capacity. One single tower can handle only so many calls. Why does this matter? It matters because the further away from said tower the more your onstar or portable cell/digital phone must increase its transmitting power to complete the call. When you get farther from the tower, you phone must kick up its transmit power. Thus it helps if you are using onstar in urban areas with many more cell towers. When a 3 watt system is very close to a cell site it transmits at roughly the same power as a hand held phone and it can put out 5 times the power from the antenna at a good distance from the site, so stay inside the car when the onstar is on. The antenna on the car is most likely tuned to help it recieve signal which means that it probably isn't got the power aimed towards the car. One might ask the dealer or onstar what type of antenna this is and how it is tuned. It may be like a quarter wave (0 dba gain, a 3 dba or a 5 dba). My guess is a 0 dba gain. Anyone know? Just my two cents.
