Radiation Safety

Radioactive Materials / X-Rays in Animals

Locations

The decision on whether animals containing radioactive material may be housed in general animal care facilities or if they must be placed in isolation rooms depends in part on the radiotoxicity of the radionuclide(s) being used and the maximum activity excreted daily per cage or per room. Radiotoxicity classifications and maximum daily excretion limits for commonly used radionuclides are summarized in Table 1 and Table 2.
