RE: TLD Response to low E

["Joe Alvarez" <jalvarez@auxier.com>]

Response will depend upon the TLD material and the thickness of the TLD. 
 The attenuation coefficient with energy is the primary consideration.  The 
thickness of the TLD will determine the depth distribution and the 
averaging over the depth.  More information is needed to fully answer your 
question.  Another consideration is the scattered electron spectrum and its 
effect on the TLD.  Co-60 has a strong forward scattered component.

Radsafe,

I would appreciate any references regarding the response, or possible
overresponse, of a bare TLD to low energy photons. (~10-20 keV).
Specifically, I am looking at the response of a  TLD outside of a lead
shielded cobalt-60 source.

Thanks
