A radioactivity shielding assembly, suitable for transferring a radioactive substance with a reduced risk of human exposure and environmental contamination, includes a protective shield casing having a reservoir disposed in the casing for receiving the radioactive substance. Associated with the casing is a coupling structure for coupling the reservoir and casing directly to a receiver into which the radioactive substance is to be transferred. The casing includes a side shielding structure in which the reservoir is retained and two end shield structures which are removably attached to the side shield structure. The two end shield structures are removed from the side shield structure at the location at which the radioactive substance is to be discharged, but such removal leaves the reservoir protectively received in the side structure to maintain continued protection against radioactive exposure or contamination. A related method of transferring the radioactive substance is also described.

A container for transporting a radioactive substance, comprising: reservoir means for holding said radioactive substance including a syringe body having a longitudinal bore and a hollow needle in communication with said bore at one end thereof and having a free end extending coaxially therefrom; plunger rod means slidably disposed in said longitudinal bore of said reserovir means; plug means disposed in said longitudinal bore in sliding sealing engagement with a wall of said bore proximate and detachably secured to one end of said plunger rod means whereby, when said plunger rod means is substantially withdrawn from said longitudinal bore at the end thereof opposite said needle, said plug means sealingly plugging the end of said longitudinal bore opposite said needle; side shield means laterally surrounding said syringe body for blocking radioactivity; coupling means, associated with said side shield means and extending therebelow, for engaging a receiver vessel to which said radioactive substance is to be transferred directly, and for providing radioactivity blocking during transfer of said radioactive substance to said receiver; bottom end shield means removably secured to said side shield means below said syringe body for blocking radioactivity during transport, said bottom end shield means defining a cavity for receiving said hollow needle; and support means for engaging said free end of said hollow needle, and for supporting said needle during transport of said container, said support means being disposed adjacent an end of said cavity opposite said syringe body, and whereby said bottom end shield means is removed for direct transfer of said radioactive substance to said receiver prior to said coupling means engaging said recieiver vessel.
