The Preparation and Properties of LiPb, a Novel Material for Shields and Collimators

The preparation and properties of LiPb are described, and its use suggested for neutron shields, collimators, filters, and antiscatter grids where gamma contamination must be kept at a minimum. The material is relatively inexpensive, easily handled and fabricated, and stable in air at temperatures over 200°C and in neutron fluxes of the order of 10¹² n/(cm² sec).
