Radiation Induced Free-Radicals for EPR Dosimetry Applications
- 3 Downloads
The performance characteristics of γ-rays dose measurements with EPR spectrometer and urotropine rods were analyzed, it were formulated as rods. The rods have significant signal that develops upon irradiation and the intensity of the signal increases with increasing absorbed radiation dose. It was observed that this material has a single EPR line. The detectable dose range was found to be 0 - 50 kGy. The dose response curves are linear up to 30 kGy. The influence of humidity, pre and post-irradiation storage under different conditions were investigated and determined.
