Rob hit many key points:



1. First point is that there should be adequate training, whereby the 

individual working in a radiation envirom=nement, is cognizant about 

what they are working with. Understanding simple laws of physics 

certainly goes a long way.



2. Know what your dosimeter can detect and accurately measure. A TLD 

and/or a CR39 can accurately detect and report neutron dose from both 

the thermal range up to about 5.5 MeV (TLD) and up to the 10 - 20 MeV 

range using the CR39. Again, it's all physics.



Thanks Rob for your comments.
