Comparative Study of the Effects of X-ray and Electron Radiations on the Optical Properties of the Solid State Nuclear Track Detector (CR-39)

Recently, the solid state nuclear track detector SSNTD (CR-39) has occupied a very important place at the top of radiation detectors for passive measurements. For this reason, many investigation were done to improve the properties of this detector. In this investigation, the energy gap of that detector was calculated by measuring the transmission at different wavelengths for ten samples. Five irradiated by electrons at different energies and the other five irradiated by X-rays at different energies in the Radiation Unit of the University Hospital of Zagzig University, Zagzig, Egypt. Another sample was used as the standard sample. The transmission for all samples was measured at the National Research Center Al-Doqe, Cairo, Egypt.
