Basic study of an effective energy measurement method using a stacked thermoluminescence dosimeter

Abstract

In this study, a method of calculating the incident photon energy from the absorbed dose ratio for different layers in a stacked thermoluminescence dosimeter (TLD) was developed. The absorbed doses for stacked TLD layers were calculated by Monte Carlo simulation for photons of various energies, and it was determined whether an approximate effective energy can be estimated based on the relationship between the incident photon energy and the absorbed dose ratio for different layer pairs. The results demonstrate that the effective energy can be estimated with reasonable accuracy using this method.
