Radiation Safety

Radioactive Materials / X-Rays in Animals

Animal Care Facilities

Once the type of location has been established, a decision must be made regarding appropriate posting of animal rooms. Outside doors to animal rooms in which radioactive material is present in quantities equal to or exceeding the quantities listed in Table 3 will require posting. The sign to be posted outside the animal room must bear the radiation hazard symbol and the words "CAUTION - RADIOACTIVE MATERIAL". Once the animal(s) and/or cage(s) contain quantities of radioactive material less than the quantities listed in Table 3, the room will no longer require posting.
