Why does radioactive material require special disposal? select all that apply.
This content will help you properly identify, store, and dispose of all radioactive waste streams that may be generated from your research, clinical, or general operations. Show Radioactive Waste IdentificationA. Radioactive waste includes:
Radioactive Waste StorageDry Solid Radioactive WasteA. Dry solid radioactive waste bins should be made of an appropriate material to provide some shielding of the radioactive waste.
B. Aqueous, non-hazardous, liquid radioactive waste may be collected in a bulk liquid container. Bulk liquid containers should be made of sturdy plastic. Bulk liquid containers should be stored within a secondary container. When full or ready for disposal, lids to all containers must be sealed completely to prevent leakage during transport. The exterior of the container should be surveyed by lab personnel for contamination. If your lab does not have an appropriate container please call EHS at (512) 471-3511 and one will be provided. Please do not use glass containers.
C. Liquid waste that is not water-soluble shall be stored in a separate container and all radioactive and non-radioactive contents be identified on a waste tag. Non-aqueous liquid waste must be separated by isotope. Mixed WasteD. Mixed waste wastes are produced by mixing radioactive materials with other hazardous substances. Producing mixed waste is prohibited without prior approval in writing by the Radiation Safety Officer E. Liquid Scintillation Vials and Cocktail Waste can poured into a bulk container following section B above if it is non-hazardous and aqueous Liquid Scintillation Vials and Cocktail Waste (Non-aqeous or mixed)F. Liquid Scintillation Vials and Cocktail Waste that is non-aqueous or contains mixed waste may be prepared as follows, as long as you have received written approval from the Radiation Safety Officer:
G. Animal Materials – No radioactive animal waste will be picked up for disposal prior to suitable deactivation of infectious agents. Radioactive animal waste shall not be autoclaved. Chemical disinfection is the only approved method. Guidelines for this process can be found in the Biological Waste section. Four types of radioactive waste are generated from animal experiments; bedding, dry, blood/urine and carcasses. Each type is to be stored separately and prepared for disposal.
Radioactive Waste DisposalA. When ready for disposal, no more radioactive waste shall be added to a container once the radiation safety office has been notified that it is ready for pick-up. B. Submit a radioactive waste pick-up (PDF) request to the Radiation Safety office at [email protected]. C. Dispose of aqueous radioactive liquid waste in sinks that have been marked as radioactive sinks. Disposal via sink must be logged in your records. These sink disposals shall be reported to the Radiation Safety Office at a minimum frequency of each quarter using the Sewer Disposal Form. D. Radioactive waste is normally picked up on the last Tuesday of each month. Labs will be notified of any deviations from that schedule. How should radioactive materials disposed?Deep geological disposal is widely agreed to be the best solution for final disposal of the most radioactive waste produced.
What are 3 ways radioactive waste disposal?Nuclear Waste Disposal Methods. Geological Disposal. The process of geological disposal centers on burrowing nuclear waste into the ground to the point where it is out of human reach. ... . Reprocessing. ... . Transmutation. ... . Space Disposal. ... . Conclusion. ... . References.. Why are radioactive wastes difficult to dispose of safely?The main issue is that the half-lives of the radioisotopes produced are very long. Some of them are greater than a million years. This makes control and management of the nuclear waste extremely difficult.
How is radioactive waste disposed quizlet?Disposal: Filtered through an ion exchange resin removing caesium and strontium (two main elements responsible for most of its radioactivity) then discharged in to the sea where radioactivity is diluted. Or it can be kept in steel containers inside concrete lined vaults.
