Investigating the impact of new dosimetric quantities recommended by ICRU 95 on the OSLD individual monitoring system at OAP, Thailand

Abstract

This research investigates the effect of new definition of operational dosimetric quantities, especially Hp(10) to Hp recommended by ICRU Report 95, on the dosimetry system. This paper focuses on the responses of two dosimeter types, nanoDot® and InLight®, using conversional coefficients from ICRU report 57 and ICRU report 95 conversion coefficients. The dosimeters were irradiated with various beam qualities, and their responses were compared to the acceptant limits provided by the IEC 62387. The results demonstrate higher responses at new definitions recommended by ICRU report 95, indicating need for the algorithm modifications in dose calculation.
