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.

X 射线和电子辐射对固态核径迹探测器 (CR-39) 光学特性影响的比较研究

最近，固态核径迹探测器SSNTD（CR-39）在被动测量的辐射探测器顶端占据了非常重要的位置。为此，进行了许多研究以改进该探测器的性能。在这项研究中，该检测器的能隙是通过测量十个样品在不同波长下的透射率来计算的。在埃及扎格齐格的扎格西格大学医院放射科，其中五个被不同能量的电子照射，另外五个被不同能量的 X 射线照射。另一个样品用作标准样品。所有样品的透射率均在埃及开罗的 Al-Doqe 国家研究中心进行测量。
