  • Publication number: 20090047656
    Abstract: The present invention provides a method of propagating cells of interest obtained from a biological specimen by a) enriching the cells under conditions that maintain sufficient cell viability; and b) propagating the cells under conditions effective to allow cell viability, proliferation and integrity.

  • Patent number: 5629525
    Abstract: A method determining the plutonium content of a material containing fluorine involves obtaining the mass ratio of plutonium in a compound comprising plutonium and fluorine, particularly plutonium tetrafluoride, to the total plutonium content. The method utilises a high resolution gamma ray spectrometry technique to obtain a count rate in a pair of gamma ray photopeaks. One of the photopeaks has an energy level of 414 keV, resulting from the decay of plutonium-239, and the other photopeak has an energy level of 583 keV, resulting from the decay of an excited sodium-22 nucleus following an (alpha,n) interaction with fluorine.
