melanoma at LLNL?, UV from lights?

[Thurman Wenzl <wenztb@worldnet.att.net>]

A few days ago someone pointed out an Am J Epi (of 3/17) article on 
malignant melanoma at Lawr Livermore; a followup to an earlier report.
They found that having jobs as chemists or 'scientists' seemed to be 
assoc with elevated risk, but they only had interiew data on ionizing 
radiation work.
Another paper referred to by Gregg Wilkinson (by Schwartzbaum et al) did 
find an assoc bet. an ionizing radiation 'index' based on measurements, 
and case status.
But: some investigators have shown melanoma to be assoc with fluorescent 
UV exposures, which at 290 nm may be different and stronger than the 
sun's UV - at least according to S Walter in the '82 AJE.
My question is: could this be part of the explanation for the building 
to building difference in melanoma at LLNL?  Do those 1966 and 1969 
buildings (pg 528 AJE, vol 145) still have the same light fixtures as 
they had in the 70s?  If so, someone could check if the UV exposures are 
any different.
