A Study of The Shielding Properties of Poly Ethylene Glycol-Lead Oxide Composite

Finely ground powdered poly ethylene glycol and lead oxide were blended together by physical mixing. Discs of polymer-metal oxide composites were prepared using hydraulic press at 200 kN pressure. The gamma ray shielding properties of these materials were determined using a 60Co -ray source. The changes in attenuation coefficient (), half value layer (HVL), tenth value layer (TVL) and relaxation length ( ) as a function of lead oxide concentration have been discussed. The results revealed that the shielding properties of poly ethylene glycol increased with the addition of lead oxide.
