Mound's thermoluminescent personnel dosimeter for neutron and photon monitoring
Technical Report
·
OSTI ID:6425946
Mound has adopted a thermoluminescent personnel neutron dosimeter to replace NTA film because of the film's poor sensitivity to lower energy neutrons. Energy calibration for the TL dosimeter is obtained from the ratio of responses of two /sup 6/LiF crystals, one filtered on the front side with cadmium and the other on the back. This permits the dosimeter to be worn in all laboratory areas without the necessity of administrative control for assigning calibration factors. A single /sup 7/LiF crystal is used to correct the two /sup 6/LiF readings for photon response. Only one /sup 7/LiF crystal is needed because both sides of it are filtered with tin, as are the non-cadmium sides of the /sup 6/LiF crystals. The former TL photon dosimeter was also redesigned and now consists of three /sup 7/LiF crystals - in the tin filtered crystal used in the neutron dosimeter, a crystal filtered on both sides with brass, and an unfiltered crystal. The holder for the neutron and photon dosimeters also contains the personnel security credential. The calibrations and performances of both dosimeters are discussed.
