Thermoluminescent neutron dosimeter with internal energy: response correction
Personnel exposures at Mound are to unmoderated and moderated neutrons from (..cap alpha..,n) reactions and to spontaneous fission and neutron induced fissions from /sup 238/Pu and /sup 252/Cf (an enriched-uranium subcritical assembly). Most of the exposure occurs in shielded glovebox lines used for processing /sup 238/PuO/sub 2/. Because the neutrons are of low average energy, it was decided that a thermoluminescent (TL) dosimeter might be a suitable replacement for film. Some TL dosimeters in use in the U.S.A. were tested along with NTA film. Internal energy calibration was a possibility with one of the TL dosimeters (Fa71) and this dosimeter became the basis for our dosimeter design. Basically, this dosimeter contains two cadmium shielded /sup 5/LiF chips with one being shielded on the source side (front shielded) and the other shielded on the wearer side (back shielded). The dosimeter also included a /sup 7/LiF chip with each of the /sup 6/LiF chips to correct the /sup 6/LiF chips for photon response.
