Measurement of the Supralinearity of exp 7 LiF Thermoluminescent Dosimeters

摘要

A study has been made of the supralinearity of the exp 7 LiF thermoluminesecent dosimeter (T.L.D.) used in the UKAEA personnel criticality dosimeter by exposure to a exp 60 Co source. the response of the T.L.D. was linear up to approximately 450 rad, above which it became increasingly supralinear, over-reading by about 50% at 2000 rad. The results have been used to produce a correction graph, as a function of apparent dose up to 3500 rad, for routine use in nuclear accident dosimetry. (Atomindex citation 09:418990)
