  1. Liquid scintillation waste containing H-3 or C-14 may be disposed of by sanitary sewer only if:

    Answer: The activity per liter and total monthly/annual discharge limits in the NRC license are not exceeded

    NRC 10 CFR 20.2003 and license conditions specify allowable concentrations and total annual discharge quantities for sewer disposal; both the concentration and total limits must be met.

  2. A radioactive waste manifest (shipping paper) for LLRW transport must include all of the following EXCEPT:

    Answer: Worker's personal dosimetry history

    Waste manifests must document the generator, waste characteristics, radionuclides, and classification, but individual worker dosimetry records are not required on shipping manifests.

  3. Generators of LLRW must keep records of radioactive waste shipments for a minimum of:

    Answer: 3 years

    NRC regulations require generators to retain records of radioactive waste shipments, including manifests, for at least 3 years, though many states require longer retention periods.

  4. Which of the following is the correct hierarchy for radioactive waste management, from most to least preferred?

    Answer: Minimize generation → Reuse/recycle → Treat → Dispose

    The preferred waste management hierarchy is to minimize waste generation first, then reuse or recycle materials, then treat to reduce hazard, and finally dispose as a last resort.

  5. Greater-than-Class-C (GTCC) LLRW differs from Class C in that it:

    Answer: Cannot be disposed of in near-surface facilities and requires deep geological disposal

    GTCC waste exceeds Class C concentration limits and cannot be safely disposed of in near-surface facilities, requiring deep geological disposal like HLW.

  6. An RSO must ensure that radioactive waste packages transported off-site meet the DOT requirements for:

    Answer: Packaging, labeling, marking, placarding, and proper shipping papers

    DOT regulations (49 CFR Parts 171-173) require that radioactive material shipments comply with packaging standards, labeling (Type A/B, white/yellow/red labels), marking, placard requirements, and shipping papers.
