Abstract: The present invention relates to highly radioactive, miniaturized, cylindrical strontium 90 titanate, strontium 90 zirconate, and strontium 90 silicate radiation sources having an activity exceeding 25 mCi/mm3, preferably ≧30 mCi/mm3, and a diameter less than 0.7 mm, preferably less than 0.4 mm. Another subject of this invention is a method for the production of these extremely small, but highly radioactive radiation sources.

Abstract: The invention describes a storage and dispatch container for variable quantities of radioactive miniature radiation sources as well as a locking and opening device for the said storage and dispatch container and is applicable for the transport of radioactive miniature radiation sources in well organized and undamaged condition.
The dispatch containers serve as storage depots at the same time and meet the requirements of radiation safety with passive protection from loss. Their construction permits automatic filling or transfer of the contents using a corresponding device.
The container is characterized in that a capillary tube (8) for the uptake of the radiation sources (15) is arranged in the main body (1) of the container and that the main body (1) exhibits a lower end-piece (2) with a fluid-medium connection (4) as well as an upper end-piece (3) with an input/output opening (3a) for the radiation sources (15), which can be locked by means of a locking mechanism (10).
