Thermoluminescence characteristics of natural rhyolite have been studied. Dose response at a wide dose range 0.5–2000 Gy has determined. Minimum detectable and thermal fading rate are evaluated. Glow curve deconvolution is conducted after determining the best read-out conditions. The repeated initial rise (RIR) method used to detect overlapping peaks, glow procedure extract thermoluminescence p...

The paper reports on the optimization of a heater used in a Thermoluminescence glow curve apparatus. Two variants of the heater, planchet system and block system, are described. Both variants performed by a cheap material as graphite and designed following cryogenic principles, are very simple constructively, ensure minimum heat losses and require

SUMMARY Preilluminated spinach chloroplasts and Chlorella pyrenoidosa, when subjected to a quick temperature jump of about 15 °, emit light. This thermoluminescence is observed both in normal and 3(3,4-dichlorophenyl)-l,l.dimethylurea.treated samples, but is absent when hydroxylamine is added to either of these samples. These results are explained in terms of a oack reaction of System II of pho...

Carbon and magnesium co-doped aluminum oxide (Al2O3:C,Mg) is a highly sensitive luminescence dosimeter with promising use in wide spectrum of radiation-related applications, including neutron dosimetry as fluorescent nuclear track detector (FNTD). The goal this work to critically evaluate diverse methods approaches for the determination kinetic parameters using Al2O3:C, Mg case study. was beta ...
