Studying the radiation protection properties of materials via γ-ray attenuation over a wide range of γ-quanta

Abstract

A setup for investigating the radiation protection properties of materials used in the manufacture of special protective clothing is described. The setup contains a collimated γ-ray source, a detector based on NaI (Tl) crystal, a movable platform for examining large areas of a material, and a data acquisition system based on a digital signal processor. A procedure for measuring the surface density of all absorbing elements in a material from the attenuation of γ-rays over a wide range of energies is described.
