> Hi, I dont know if I read in too much in this but I share my thoughts anyway. 2.5 REM as absorbed dose of radiation is what you get by just living in my part of the world for approximately 5 years. I live in Sweden and I dont think we have more PWPs here than the rest of the world. So I think it is difficult to find any linkage between such a dose and parkinson, but of course you can never be sure. > > Best regards Micce Granstrom Micce The 2.5 REM is in addition to natural background. What I'm interested in is a regional break down per capita, because natural occuring backgroud differs based on alot of different things. I'm not sure what background is in Sweden but I do know that the NE US has a significantly higher level than Hawaii and other areas of the US also vary widely. It's just a thought.
