Searching for TL/OSL Dose Rate Effects in Various Luminescent Materials

The goal of the present work was to conduct an initial screening survey of several types of TL and OSL detectors, aimed at searching for the indication of the presence of dose rate effects. The study has been performed on ten different materials: LiF:Mg,Ti; LiF:Mg,Cu,P; CaF2:Dy; 2 :Dy; Al-P glass; YAP:Mn; CaSO4:Dy; 4 :Dy; Al2O3:C; 2 O 3 :C; BeO; MgB4O7: 4 O 7 : Ce.Li and quartz. Gamma-ray dose rates ranged from 0.1 mGy/h to 90 Gy/h. No clear evidence of dose rate effects was found for any material. In two cases (MgB4O7: 4 O 7 : Ce,Li and BeO) some irregularities of the response were observed, which require further investigations but most probably they are not attributable to the dose rate influence.
