Abstract
A radiation protective material comprises at least 50% of an inorganic lead compound and at least one compound of a rare earth metal. The compound of the rare earth metal, preferably a salt, e.g. cerium phosphate, may form part of a naturally occurring rare earth mineral which may be used in the unpurified state. When monazite is used as the rare earth mineral it advantageously constitutes 20 to 50% by weight of the dry radiation protective material. The material may include zirconium sand and/or ilmenite, and also zirconium dioxide and/or titanium dioxide. The material may be mixed with a plasticizer, e.g. bentonite or tragacanth, pressed and then sintered at an elevated temperature to form a moulded refractory article.
