RE: Individual monitoring device question.

["Jim F. Herrold" <Herrold@uwyo.edu>]

Thanks, Sandy. You've proved my point. I did not say that the dosimetry
provider had all the answers. In my dictionary, consult means to "converse
or advise together." Without CONSULTING with them, how can you blindly
determine where the badge should be worn, and how can they interpret the
results? They are the experts on dosimetry technology, they are accredited
to interpret the badge readings, they must know your needs in order to
provide the best service.

Landauer was happy to consult with me years ago on this very issue. We had
employees whose most likely area of exposure was waist high. We consulted
with Landauer and changed their type of badge. Landauer SAID they need to
know where the badge is worn in order to calculate doses to other parts of
the body (y'know, inverse square law, etc.). It was not just a matter of
convenience. Based on this knowledge that I received as a fledgling RSO, I
included the information in my radiation safety training. Before I became a
Health Physicist, no one told me not to wear my G1 badge on my belt, or hat
or shoe. I, and every other tech, wore them wherever we wanted.

Jim,

I take exception to your comment. The dosimetry provider is not the 
right group to determine where the dosimeter should be worn. Only the 
facility that knows how the individual will be irradiated, geometry, 
etc., can make that determination. I as a processor do not have a 
clue as to how it is worn, or where the individual works. I am not 
the right person to direct badge location. We can assist in a 
discussion though, but in the end, it is not our decision.  What you 
have stated only refers to a badge label which identifies where the 
facility says they are going to wear the badge. This is for 
convenience, and has nothing to do with the characteristics of the 
dosimeter, regardless of who the provider is (assumes that the 
dosimeter has the same elements, be it TLD, film, etc.) 

In conclusion, only the facility can make the determination as to 
where the badge should be worn.
