Re: external dosimeter measurement accuracy

     Accuracy is determined by the efforts put into developing the specific 
     dose algorithms for the specific type TLD or Film Badge utilized. I 
     suggest that you refer to ANSI N13.11 which addresses performance 
     testing requirements. I also suggest that you obtain a copy of "A 
     Comprehensive Set of Conversion Coefficients for Photons" by Chris 
     Soares, dated April 21, 1995. From my own data, it can be demonstrated 
     that when blind testing is conducted with a NIST facility, that 
     accuracy can be attained within +/- 2% across all 9 NVLAP testing 
     categories. In summary, the answer you're looking for is dependent on 
     WHO does the processing, and how good a TQM program is in place. 
     
     If you would like more specific discussions, call me. I will be happy 
     to discuss this topic with you or anyone else who might be interested.

Does anyone out there have information concerning measurement accuracy
(e.g. 95% C.L.) for external radiation dosimeters such as film badge or TLDs?
I also need appropriate references. Thanks. Ken Mossman
