Re: To Luxel Users

Another thought. NVLAP requires that each dosimeter have an LLD 
determined for the various radiation types (mixtures not included in 
the test). If the dose is reported 1 mrem, the LLD calculation must 
demonstrate that the dose reported is valid. If the users see a 
variance in background in their own facility, also be aware that 
there is increased background from transit exposure. If the Control 
Badge is not situated within the shipment where each dosimeter 
being shipped along with the Control Badge, there is a strong 
potential that the shipment is not irradiated evenly, and then take 
into account potential medial pharmaceuticals also being shipped. 
There will be false positives, believe me.

So, does anyone have the LLD calculations .. what about the 
measurement of uncertainty calculations for the process?
