تعیین میزان دز جذب‌شدۀ پرتو گاما به روش PTTL با استفاده از آشکارساز α-Al2O3:C

Phototransferred thermoluminescence (PTTL) was used to reeestimate the absorbed gamma dose in α-Al2O3:C dosimeter. The PTTL response of this phosphor for different UVB irradiation times was investigated. The results show a linear PTTL response for gamma absorbed doses from 0.1 to 14 mGy. Because of high PTTL sensitivity in this phosphor, the low limit of re-estimated gamma dose using PTTL method is very low compared to other phosphors.
