Abstract
A shield against ionizing radiations comprises at least one layer including one or more boron minerals and/or one or more lead minerals and/or directly derived products, which preferably constitute the inert or slightly active aggregate fraction of cement-based conglomerates (such as concrete or mortar). Galena and/or other lead minerals can be used for the shielding from .gamma. rays, and colemanite and/or other boron minerals can be used for neutron shielding. Particular purpose additives will also be used. The family of compositions according to the invention will contain by weight 65-75% of floated galena, 5-10% of colemanite and 20-25% of binding agents and additives.
