Jim, I agree with the above. I do however see this discussion with 
the vendor mostly occurring under abnormal radiation situations. I 
see the facility making the determination as to where the badge 
should be worn based on the applications involved, and then 
addressing the badge configuration, identifying badge location on the 
label, with the vendor, after the initial information has been 
gained.

What most wearers don't understand is that because a film, or TLD, 
has a different location to be worn, doesn't mean it's a different 
configuration. What is important to know, from a set-up, is the type 
of field to which one will be exposed, i.e., radiation type, energy 
spectra, etc. That will determine TLD element type, i.e., TLD 100, 
TLD 600 or TLD 700, as an example. The beta energy is important, as 
is the neutron spectra. Film is film, and the only differencxe is 
where it's worn,, and is there an angular incident photon or x-ray, 
that needs to be considerd.  These are all issues in defining the 
type of badge to be worn. The location, for the badge type, isn't as 
important, unless there is again, an abnormal irradiation, which the 
vendor must then consider in the dose evaluation (if appropriate).

Sandy
