| General Information |
| |
In the planning stages of your experiment, review disposal procedures with your Area Health Physicist, 301-496-5774. For assistance about radioactive waste, policies, and procedures, call 301-496-5774.
|
| Segregate |
- Liquid waste from dry waste
- Short half-life (< 120 days) from long (>120 days) half-life waste. For multihazardous (mixed) wastes, see segregation policy in Multihazardous Waste Section
- Aqueous solutions from mixed wastes Waste containing chloroform or trichloroacetic acid (TCA) from any other aqueous radioactive waste
|
| Adjust |
- Liquid waste solutions should be adjusted to a pH between 6 and 10. Use caution; call your Safety and Health Specialist (301-496-2346) for assistance
- For disposal of radioactive liquids with pH <3 or >12, refer to the Multihazardous Waste Section
|
| Identify and label |
- List on the Radioactive Waste Pickup Receipt an ACCURATE indication of radionuclide(s) and activity
- Ensure that all radioactive waste containers have a:
-Caution -Radioactive Material label (NSN-7690-00-833-0318) and
-Radioactive Waste Pickup Receipt (NSN-7530-00-LO7-8835)
|
| Shield |
- Shield radioactive material such that:
Radiation levels are less than 2.5 millirem/hour within a posted laboratory, AND radiation levels are less than 2.0 millirem/hour or 50 millirem in a year in any unrestricted area (e.g., space adjacent to a posted laboratory)
|
| Waste Storage |
- NEVER place radioactive waste in corridors - even while awaiting pickup
- Ensure that all waste containers are closed securely
|
| Security |
- Radioactive materials must be secured or held under constant surveillance to prevent unauthorized removal or access
- Source vials must be stored in a locked container at all times
- Consult your Health Physicist, 301-496-5774, for more information
|
| Containers and pickup |
- Call Radioactive Waste Service, 301-496-4451, for containers and waste pickup
