SIMPLIFICATION OF THE PROCEDURE FOR REUSE OF LIF-MG,CU,P TL DETECTORS

LiF(Mg,Cu,P) TL detectors have been re-used in two ways: without annea ling and with an annealing of 90 s in a TL reader in the dose range of 3 x 10(-4) - 0.1 Gy. No change of TL sensitivity and dosimetric prope rties was observed. The residual TL signal without annealing was about 4% after each measurement, and the coefficient of variation of the se nsitivity was 2.2% after ten cycles of re-use. The residual signal wit h TL reader annealing is between 0.16 and 0.23%. The simplified re-use procedure is of significance if it is applied properly to the routine applications of personal and environmental monitoring.
