✍️ Sample NRRPT Questions & Answers

1. What is the NRC's occupational dose limit for the lens of the eye per year?
✓ 150 mSv

The NRC sets the annual occupational dose limit for the lens of the eye at 150 mSv (15 rem) per 10 CFR 20.1201.

2. A nuclear power plant's Technical Specifications (Tech Specs) are legally binding because they are:
✓ Incorporated into the operating license as Appendix A

Technical Specifications are incorporated as Appendix A of the facility's NRC operating license, making them legally enforceable license conditions.

3. What is the derived air concentration (DAC) used for in internal dosimetry?
✓ To establish the airborne concentration that equals one ALI when inhaled for a full work year

The DAC is the airborne radionuclide concentration that, if breathed for 2,000 hours, would deliver one annual limit on intake (ALI).

4. What is the purpose of a 'two-person rule' in high radiation areas?
✓ To ensure a second person is present to assist or get help in the event of an emergency

The two-person rule in high radiation areas ensures that if one worker becomes incapacitated, the second can provide assistance or summon emergency help.

5. A 17-year-old student is working in a lab under an NRC license. What are their annual occupational dose limits compared to an adult worker?
✓ 10 percent of the adult limits

According to 10 CFR 20.1207, the annual occupational dose limits for minors (individuals under 18 years of age) are 10 percent of the annual dose limits specified for adult workers. This means their total effective dose equivalent limit would be 0.5 rem (5 mSv).

6. When using the 'point source' approximation to estimate shielding requirements, which condition invalidates this approximation?
✓ When the source dimensions are comparable to or larger than the distance to the point of interest

The point source approximation is only valid when the source is small compared to the distance to the receptor; for distributed sources, more complex geometric calculations are required.
