2. Protect yourself and others from radiation exposure.

3. Store radioactive waste in a protected and confined area.

4. Store separately liquid and dry waste. Separate sharps.

5. Separate waste according to the half-life of different isotopes (e.g., < 15 days: 32P, 131I; > 15 days and < 90 days: 33P, 35S; > 90 days: 3H, 14C).

6. Radioactive waste may be disposed as normal waste after being stored for more than 10 half-lives. Contact your local radiation safety office for disposal.

7. Animal tissues and carcasses may be wrapped in waste safe and frozen temporarily.

8. Document usage and disposal.
