Re: Military Ship Radar

Dear Radsafers:
	The Robinette study indeed contains a great deal of information 
about long-term risks associated with use of Naval radar during the 
Korean War.  The abstract is misleading, reading" No adverse effects 
were detected in these indices (deaths by cause, disability, and 
hospitalization) that could be attributed to potential microwave 
radiation exposure in 1950-1954".  Dr. Charlotte Silverman, an 
epidemiologist and second author wrote in the Bull. N.Y Acad.Med. vol.55, 
1979, "While some significant differences among the occupational groups 
classified by level of potential exposure have been found with respect to 
all of the  endpoints studied, the differences could not be interpreted 
as a direct result of microwave exposure."
	I have reanalyzed the data in the article myself, prior to seeing 
Dr. Silverman's comment, and came to the same conclusion that she did.
The study shows important and significantly positive associations, 
and critical associations are all significantly positive, but the exposure
estimates were of potential, not measured, levels, and hence a DIRECT causal
relationship cannot be shown.
