Title Neutron shielding - some recent developments
Bibliographic information Mar. 1984, No.57, p.19-24. Illus. 10 ref.
Abstract Description of shielding devised against intense neutron sources, such as americium-beryllium sources used in oil exploration (aboard offshore drilling platforms, with a shield weight limit of 5 tonnes), and proton cyclotrons used for neutron therapy in hospitals. An inner core of lead shielding surrounded by a layer of a new product (KAYDEX LS), containing a high level of lithium and rich in hydrogen and having a total weight of 2 tonnes, was adequate protection against neutrons and secondary radiations from americium-beryllium sources. Earth materials and a labyrinth-like arrangement of treatment areas was the preferred solution for neutron-therapy areas in hospitals.
