Thermoluminescence (TL) dosimetric characteristics of pink Himalayan salt from Khewra, Pakistan
摘要
In the present study, the dosimetric features of pink Himalayan salt pellets were studied. Energy dependence exhibited an over response up to 100 keV with a maximum factor of ~ 10 at 33 keV. The maximum angular dependence of ~ 46% was observed at 90° angle of incidence. The TL response was found to be dose rate independent and showed a good reproducibility with < 5% COV. The sample sensitivity was comparable to TLD-100 (beyond 500 mGy). The effective atomic number (Zeff) was found to be 15.20. Based on these dosimetric features, pink Himalayan salt can be a good potential candidate for therapeutic dosimetry applications.
