Optimization of the readout procedures for the Harshaw 8800 TL (thermoluminescent) dosimetry system
- James
The optimization of the readout procedures for Harshaw's LiF-TLDs and it 8800 automatic TLD reader were studied. The optimization was based on the TLD sensitivity stability during 8-10 recycling uses. Three types of TLDs under several exposure conditions (gamma and neutron, low and high doses, and different fading times), five different types of TL light signals, and three different heating time-temperature-profiles (TTPs) were involved in the stability performance studies. The results show that the optimum readout procedures for all exposure cases can be achieved by using the Harshaw-suggested TTP heating methods and the TL light signals of some certain carefully-chosen regions of interest and peaks 3+4+5. The practical experience gained from using the computerized glow curve deconvolution (CGCD) program in the reader is also discussed. 17 refs., 5 figs., 6 tabs.
