A radioaerosol delivery apparatus particularly adapted for the subsequent disposal of radioactively contaminated elements is described. The apparatus includes a shielding container including an outer shell and an inner shell supported within the outer shell. The inner shell is formed with an inner wall and an outer wall defining a space therebetween for receiving radiation shielding material. The inner wall is formed to provide a surface conforming substantially to the contour of the radioaerosol source and a surface conforming substantially to the contour of a portion of a transport manifold supported thereon. A removable cover including radiating shielding material is formed with a portion conforming generally to the contour of the transport manifold. The inner wall of the container and the cover define at least one opening therebetween to permit fluid communication from the transport manifold to a patient utilizing the apparatus.

A full viewing shielding holder for radionuclid disposable plastic syringes is disclosed. Maximum light gathering for illumination of the syringe scale and clear visibility of that scale in any relatively rotated position of the holder and of the syringe therein are afforded by the improved holder comprising a tubular body of radiation shielding glass translucent and optically polished substantially throughout its circumference and length and having a quickly engageable and disengageable syringe gripping means fitted on one end thereof. In one disclosed embodiment the releasable gripping means comprises a rubber 'O'-ring compressible against the syringe body by a clamping means to hold the syringe in place by friction. In a second embodiment the releasable gripping means comprises an internally threaded fitting cooperating with an element on the syringe. When the syringe is inserted into the holder, a slightly tapered annular flange on the end of the syringe enters the fitting snugly, whereupon turning of the syringe with insertion pressure continued causes self-threading of the fitting in the soft flange material to hold the syringe releasably.
