Radiation Dosimeter Using Peroxy Radicals in Irradiated Polytetrafluoroethylene

Abstract
A new method of radiation dosimetry using peroxy radicals in irradiated polytetrafluoroethylene (PTFE) has been developed. The PTFE used is in powder form. The results show that this dosimeter is useful for both electron and 60Co gamma-ray irradiation. The concentration of the peroxy radicals linearly increases with dose up to 100 Mrads and does not depend on the dose-rate. The peroxy radicals formed by irradiation are stable during prolonged storage, and handling of the sample is easy. The behavior of the peroxy radicals in the irradiated PTFE is discussed.
