Re: Mobile phones & brain tumors

["Richard L. Hess" <lists@richardhess.com>]

Hello, Bjorn,



This study arrives at different conclusions, it seems, than the previous work.



The interesting item in the previous post is that presumably the radio worn 

by the driving examiner is a lower frequency unit than cell phones which 

start at about 900 Mhz and go up from there.



Also, cell phones are transmitting (even when not talking) and 

communicating with the cell site. The typical usage of cell phones (long 

conversations) is generally much different than the short communications of 

public-service type radio.



I caution about any inferences to the previous question drawn from cell 

phone usage. The technical differences are great.



While I cannot say it doesn't exist,  I have not heard of a study or 

concern among public safety officers about radio usage and cancer.



There _may_ be (and again, I don't know of any real studies) some concern 

about people who spend long periods at high-power broadcast transmitter 

sites,  but, then again, most of the time they are inside well-shielded 

buildings where the signal level is lower than on a normal street.



My own opinion...not speaking for anyone else.



Cheers,



Richard
