Biomedical waste disposal--Nuclear Regulatory Commission. Final rule

The NRC is amending its regulations to permit licensees greater leeway in disposing of liquid scintillation media and animal carcasses containing tracer levels of hydrogen-3 (tritium) or carbon-14. These rule changes will primarily affect NRC licensed hospitals and medical research institutions. Most licensees presently dispose of these items by sending them to a radioactive waste burial ground or by obtaining special authorization from NRC for incineration or onsite burial. Under the new regulations, the licensee may dispose of specified concentrations of these materials without regard to their radioactivity. The NRC is also amending its regulations to raise the annual limits for disposal of hydrogen-3 and carbon-14 by release to the sanitary sewerage systems. The rule changes will conserve waste burial capacity that is already in short supply.
