42 Radiation for Radionuclide Users report, whether or not they meet the aforementioned monitoring requirement. This report normally is the Nuclear Regulatory Commissions’ NRC Form 5 or equivalent . Emergency And Decontamination Procedures Despite the strict adherence to all laboratory safety rules, it is possible that accidents involving radioactive material will occur on occasion. For this reason, it is important that radioactive material users are aware of the proper procedures to follow for various types of accidents. Minor Spills Incidents involving the release or spillage of less than 100 microcuries of a radionuclide in a nonvolatile form can generally be regarded as minor. In such cases: 1. Notify all other persons in the room at once. 2. Clear the room of all persons except those needed to deal with the spill. 3. Confine the spill immediately. 4. Liquids: Drop absorbent paper or chemical (e.g. calcium bentonite) on the spill. Solids: Dampen thoroughly, taking care not to spread contamination. Use water, unless a chemical reaction would release air contaminants; otherwise use oil. 5. Notify the laboratory supervisor. 6. Notify the Radiation Safety Officer (RSO) or EH&S. Major Spills or Releases An incident which occurs outside of the hood and involves the release of more than 100 microcuries of a radionuclide in a nonvolatile form, or the release of any amount of a radionuclide in a volatile form, should be considered “major.” In such cases: 1. Evacuate the room immediately shutting doors and windows on the way out. 2. Notify the laboratory supervisor. 3. Notify the RSO or EH&S 4. Post the laboratory door with a “Keep Out” sign. Assemble those persons who were present in the laboratory near the entrance. 5. Wait for assistance.
