A shielded facility for storage and handling of up to 100 ..mu..g of Cf-252 seed assemblies, afterloading cells and tubes, and a remote afterloader using four tubes totaling 60 ..mu..g were designed and constructed. The radiation protection survey of the completed facility was performed, and applicability of a guide for spherical shields was confirmed by the present design calculation and survey. For local shielding such as bedside shielding, however, the guide cannot be applied because scattered neutrons from the floor, ceiling, and wall may reach behind the shield. This paper describes the treatment planning method for Cf-252 implants with the aid of a computer.
