Re: Dosimeter Location
I have been following this thread with some interest. Why as a professional
do we need something in writing on which to base a common sense decision
that should be based on first principles of Radiation Safety and Protection?
Ron Kathern is on track on this one ... as usual RON!
I don't remember the place of publication but Libby Brateman has done
extensive work on wearing of dosimeters outside, inside, at the collar, etc.
Will look it up. Her work in this area is excellent and should be read by
all grad students and those who have such interest. .... I will dig out the
reference later and post it .... IF SOMEONE doesn't beat me to the punch.
