Linear attenuation coefficient measurement in polymer composite

الملخص EN

Linear attenuation coefficient of polymer composite for beta particles and bremsstrahlung ray were investigated as a function of the absorber thickness and energy.

The attenuation coefficient were obtained using NaI (Tl) energy selective scintillation counter with 90Sr / 90Y beta source having an energy range from 0.1-1.1 MeV.

The present results show the capability of this composite to absorber beta particles and bremsstrahlung ray that yield from it.

That’s mean it is useful to choice this composite for radiation shielding of beta ray with low thickness.
