Abstract

A new high-density material is evaluated for use as shielding at medical radiation therapy facilities. The substance is supplied in the form of prefabricated interlocking blocks that contain steel scrap as the aggregate in a matrix of Portland cement. This material, called Ledite by its manufacturer, permits the dimensions of radiation therapy room walls to be reduced by a factor of approximately 2 when compared with rooms made from ordinary concrete. The neutron absorption required for high-energy linear accelerators is present.
