1. Do you use neutron electron dosimetry? Yes. 2. If yes, what model / manufacturer? DMC2000GN/MGP. We have DMC3000 EDs (mode G3) with neutron modules but haven't used them yet. Plan to test this spring. 3. Where / when is it used? Containment entries/DW entries/Dry Fuel Storage campaigns. Used at all Duke sites. 4. How does it compare to DLR (i.e. TLD, OSL) reads? Very well about 85% or the time. 5. Are you able to eliminate [neutron] paper tracking methods with the electronic dosimeter? No. Sentinel does not support DMC2000GNs or DMC3000 mode G3). 6. Do you have a correction factor? If yes, what is it? We have developed CFs for areas where thermal neutrons are significant but haven't used them yet. TLD very conservative in those situations. 7. Would you be willing to share technical information on determining your correction factor? Sure.
