RE: where to wear a dosimeter (Bernie's comments)

["Stokes, James" <StokesJ@TTNUS.COM>]

 In fact, I was a SG jumper in the 1980's. We had to wear five dosimters on

our head, one on front chest, one on back, one on each thigh, and rings on

all fingers.  This was because the radiaition levels varied so greatly

inside the SG bowl, with levels as high as 17,000 mR/hr in many spots.  The

highest of the head,chest,back, and thighs, were recorded on a daily basis

as the Whole body dose for the period.

I agree. And, the body is defined in the regulations as the highest 

area where the whole body dose is, prior to the current revised 

10CFR20.101(a), and, the whole body was defined as "whole body, head 

and trunk, active blood forming organs, lens of eye or gonads."  

Therefore, if the highest dose was to the head, then the dosimeter is 

required to be worn there. Doesn't anyone remember the root cause for 

mulitbadging back in the early 80s?  San Onofre .. SG Jumpers NOT 

wearing a TLD on the head, to measure the highest dose.
