General handling precautions for Yttrium-90 1. Designate area for handling 90Y and clearly label all containers. 2. Store 90Y behind lead shielding. 3. Wear extremity and whole body dosimeters while han-dling mCi (37 MBq) quantities. 4. Handle millicurie (37 MBq) quantities of 90Y behind 1.3-cm (0.5-in) thick Lucite® shielding. Where necessary, Biological behavior of yttrium. Early interest in yttrium 90, and in some of the radioactive rare earths, centered about the use of colloids of these elements to achieve selective irra-. diation of bone marrow, liver, spleen and lymph nodes.

1 Decay Scheme. Y-90 decays by beta minus emission, mainly to the Zr-90 ground state, with a small branch to the level at 1760 keV. L’yttrium 90 se desintegre par emission b^eta moins principalement vers le niveau fondamental du zirco- nium 90, il existe une faible branche vers le niveau excite de 1760 keV. Yttrium-90 is produced by the nuclear decay of strontium-90 which has a half-life of nearly 29 years and is a fission product of uranium used in nuclear reactors. As the strontium-90 decays, chemical high-purity separation is used to isolate the yttrium-90 before precipitation . Exposure to yttrium-90 and yttrium-91 from radioactive fallout is not expected to be important (SRC), because of the short half-lives of these yttrium radionuclides, half-lives for yttrium-90 and -91 are 2.67 and 58.5 days, respectively (2), and the low concentrations of these substances in the environment (3).
