Dosimeter / TLD / OSL Quick info check BWR / PWR /other -PWR Electronic dosimeter (ED) calibration correction factor(s) value -+10% for deep dose dosimeter for legal record TLD / OSL / other - TLD Average (estimated or dominant) photon energy -Estimated average (my guess) 500 to 800 keV, higher in containment at power due to N-16 Does the typical photon energy encountered change significantly (200 -300 kev) during refueling outages - I suspect slight increase in average energy. typical ED / TLD (OSL) ratio - 0.95 to 1.05. For 2011, overall ED/TLD was +0.8% for non-zero TLDs If change from TLD to OSL/other was ED correction factor changed - Have not changed from TLD. thanks for your time, Benjy Benjy Bertossi Fermi2 - RP Supervisor 734-586-4935 [email protected]
