Re[2]: textbook correct?

     Agreed, radiation carcinogenesis is a subject of great interest to all 
     radiological scientists.  Unfortunately, I can provide little help 
     with references showing no association between radiation and cancer.  
     There was a paper by Ted Webster, American Journal of Roentgenology 
     137:647, 1981.
     
     The American College of Radiology is at 1891 Preston White Drive, 
     Reston VA 20191-4397, USA.  The telephone is 703-648-8900, FAX 
     703-648-0234.
     
     Best wishes.

This is a subject of great interest to hospital RSO's:

I've seen the list of references in a 1995 NRPB document to the studies of 
patients who had chest fluoroscopy and other procedures, showing a weak 
association between cancer risk and exposure. I'd also like references to 
good epidemiological studies which demonstrate no association between 
cancer and medical xray exposures where total tissue doses were in the 
'intermediate' range, say 50 mGy to a few hundred mGy (bad old days?). 
Could someone please give me a contact address for the publications section 
of the American College of Radiology?
     
Thank you,
