Abstract

In this work, the attenuation coefficient and mean free path of 60, 290, 404, 566 and 662 keV gif.latex?\gamma-rays for PbWO4 and CdWO4 scintillation crystals were measured using the transmission method. The 60 and 662 keV gif.latex?\gamma-rays were obtained from 241Am and 137Cs radioactive sources, respectively. The 290, 404 and 566 keV g-rays were obtained from the Compton scattering of 662 keV gif.latex?\gamma-rays (137Cs source) at scattering angle of 90°, 60° and 30°, respectively. For comparison, the attenuation coefficient and mean free path of gamma rays for the studied crystals were also calculated over energy range 1 – 1000 keV using the WinXCom program.
