A systematic study of the attenuation (absorption) of electromagnetic radiation in Nuclear Track Detectors (NTDs) is carried out. The attenuation of gamma rays, X-rays, UV and visible radiations in NTDs are investigated using NaI(Tl) detector, Gas Electron Multiplier (GEM) detector and UV-Vis spectrophotometer respectively. The values of some important parameters (e.g., mass attenuation coefficient, optical depth) of three commercially available NTDs (PET, Makrofol and CR-39), at the relevant regions of the electromagnetic spectrum, are determined. The details of the experimental techniques and the results are also presented in this report.

对核径迹探测器 (NTD) 中电磁辐射的衰减（吸收）进行了系统研究。分别使用 NaI(Tl) 检测器、气体电子倍增器 (GEM) 检测器和紫外-可见分光光度计研究了 NTD 中伽马射线、X 射线、紫外和可见辐射的衰减。在电磁波谱的相关区域，确定了三种市售 NTD（PET、Makrofol 和 CR-39）的一些重要参数（例如，质量衰减系数、光学深度）的值。本报告还介绍了实验技术和结果的详细信息。
