Abstract

This study examines the feasibility of utilizing pure polycrystalline alanine-in-glass tubes as commercial dosimeters. The design of the dosimeters avoids preparation complications such as mortaring, sieving, and/or binder addition. It also reduces several fabrication techniques of alanine dosimeters and hence it allows other laboratories to conduct similar electron paramagnetic resonance (EPR) measurements. The dosimeters were irradiated with gamma rays ranging from 0 to 20 Gy. The dosimeters were found to be more sensitive to low radiation doses than other types of alaninewith- binder dosimeters. They exhibited a linear response in the dose range from 0.1 to 20 Gy. These positive properties favor the pure polycrystalline alanine-in-glass tube as a radiation dosimeter for low gamma irradiation doses.
