Specially Adapted Containers Or Shipping Cask Handling Devices (e.g., Transporting Devices) [g21f-5/00n] Patents (Class 976/DIG352)
  • Patent number: 6166284
    Abstract: The present invention is directed to a material-radioactive isotope combination, comprising a container made from a material and a radioactive isotope solution. The container is useful for the storage, shipment, or storage and shipment of the radioactive isotope. Preferably the material is characterized by having a nearly full compliment of double carbon bonds so that little, or no hydrogen is produced by the material in the presence of the radioactive isotope. Furthermore, the preferred material exhibits greater mechanical strength than that of glass, resistance to a temperature range of from about -40.degree. to about 160.degree. C., chemical inertness; and radiation resistance. An example of such materials includes PSF (polysulfone) and PETG (polyethylene terephalate G copolymer) and the radioactive isotope, of the material-radioactive isotope combination are selected from, the group consisting of Mo-99, I-131, I-125. W-188 and Cr-51.
