Abstract
When ordinary sugar is exposed to ionizing radiation, a number of free radical are created in sugar, and Electron Paramagnetic Resonance (EPR) signal appears from the sugar because of the paramagnetic property of free radical. In this paper, EPR signal intensity has been measured in x-ray irradiated sugar for various absorbed doses, irradiated dose up to 50 Gy. The EPR intensity signals are increased as the x-ray irradiation increases. Also, the fading value decreased to about 3% in 30day after the irradiation. Therefore, the sugar is a useful material for emergency dosimeter as the free radical dosimetry with the EPR equipment.
