  • Title: Impurities of 99mTc-generators.
    Author: Näsman P, Väyrynen T.
    Journal: Eur J Nucl Med; 1983; 8(1):26-9. PubMed ID: 6832185.
    Abstract:
    The impurities present after use in 99Mo- 99mTc-generators produced by four different manufacturers were investigated by means of the energy spectrum and half-life measurements. The generators produced with fission contained only a few impurities, and the half-lives of their nuclides were relatively short. The only generator manufactured using neutron bombardment contained several nuclides whose half-lives were in a range of a few months, but also a 60Co nuclide whose long half-life may give rise to difficulties in destroying the generator.
