When I was in graduate school, a number of the older professors
(some educated on the GI Bill post WWII and Korea) had done
at places like Rocky Mountain Arsenal, slinging radio-isotopes in
amounts that would send any sane person running for a very deep cave.
BUT...it was their fellow professors from depts. of Art or PoliSci that would
drop by to say "Well, I'm dying of cancer".
From what I could tell, it was far more dangerous to have a life of
wine, women, song and cigarettes...than pipetting radio-isotopes.
I went to the wrong poli sci school for undergrad. A few profs smoked, but wine, women and song were nonexistent. Some of the Peace Studies womyn would bare their breasts in protest every once in a while. /shudder/
