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

This research investigates the effects of new definitions of operational dosimetric quantities, especially(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.

Establishing of primary standard for Cs-137 air-kerma of OAP, Thailand.

Graphite wall cavity chambers are the most common detector for precise gamma-ray measurement and are accepted as primary standards for radiation protection and radiotherapy level beams. This paper describes the physical constants and the evaluation of the correction factors that are necessary for the graphite cavity chamber to be established as a primary standard of the Office of Atoms for Peace (OAP). The correction factors to be applied to the primary standards were determined by experimental and Monte Carlo methods.
