ABSTRACT:
A vacuum force is applied to simplify the routine of pick-up and handling of radioactive seeds, singly or in groups, and to quickly and safely transfer the seeds into a shielded direct-coupled holding vial. The shielded holding vial is part of a hand held probe which can be detached quickly and interchanged with another empty shielded holding vial, thereby permitting the sorting or separating of radioactive seeds into different groups. Due to its quick pick-up ability, light weight and quick-coupling shielded storage vial, the spring loaded probe can greatly reduce the pick-up and transfer time and hence, eliminate radiation exposure to an individual. As a simple vacuum transfer pick-up, the spring loaded probe is provided with an adaptive mouthpiece which permits manipulation of radioactive seeds, within a shielded area. In addition, the handling of small objects including non-radioactive objects such as TLD chips commonly used in radiation or radiation measurement areas is achieved. To further eliminate radiation exposure to personnel handling loose seeds, the top portion of the hand-held spring loaded probe is made with a direct-coupling companion shielded holding vial, which acts as a receptacle to collect seeds. The shielded holding vial can be "un-coupled" quickly and easily so that multiple shielded holding vials may be used with the spring loaded probe to sort groups of radioactive seeds into several designated shielded holding vials.
