Effect of temperature on the epr response of gamma irradiated potassium tartrate hemihydrate

Electron paramagnetic resonance (EPR) can be used as radiation detection for appropriate materials exposed to ionizing radiation. In this study, potassium tartrate hemihydrate (PT) was irradiated with Co-60 gamma rays with absorbed dose range from 1 to 9 Gy. The effect of temperature to the unirradi...
