Gamma dosimetry with CR-39 etch track detector

To preserve and improve the safety of food for commercial purposes, it is e xposed to high gamma-ray doses. The gammaray doses used for this purpose ra nge from 0.15 kGy to 510 kGy. At such high doses, the etching characteristi cs of CR-39 are severely affected. This property, therefore, can be used to develop a CR-39-based gamma dosimeter. In this context, systematic studies were carried out and the bulk etching rate was determined as a function of gamma-ray dose using different methods.
