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