Radiation shielding composites using thermoplastic polymers mouldable at low temperature

Abstract

The formulation of a low temperature thermoplastic mouldable radiation shielding composite is given. The material is based on a low temperature melting polymer filled with lead shot. It can be easily moulded to shape after immersing in hot water, or by using a hot air gun. When cooled it is a rigid self supporting mass. Alternative formulations to provide low background or low toxicity gamma shielding or neutron shielding are also considered.
