Dear Otto,
Perhaps you have noticed that beneficial effects seems to be narrowly 
interpreted to reduction of cancer which is hard to prove because of 
the complexity of cancer and the many causes of cancer, such as 

The strongest evidence of health benefits of radiation is the greatly 
reduced deaths from non-cancer as shown in the nuclear shipyard 
worker and the 100 -year study of British radiologists. Even the 
earliest UK radiologists (1897-1920) with a 75% increase in cancer 
had a significant decrease of deaths from non-cancer. Their longevity 
was slightly longer (NS) than their medical colleagues.

The decrease in non-cancer is easiest to understand by the public in 
terms of increased longevity. See my article:  Cameron, J.R. 
Longevity is the most appropriate measure of health effects of 
radiation,  Radiology 229, 14-16 (2003).

The death rate from non-cancer for 28,000 nuclear shipyard workers 
with the greatest cumulative doses was 31% lower than that of the 
32,500 unexposed controls. (16 std dev or p<10^-16) This results in  
an increase of longevity of about three years.
The non-cancer death rate of the UK radiologists who joined a 
radiological society between 1955-1979 is 36% lower  (p<0.001) than 
that of other UK MDs. 
It seems to me that radiation health scientists should look at the 
real bottom line! I welcome your comments.

Best wishes,

John Cameron

they have been corrected for age distribution.
