Under 10 CFR Part 20, what is the annual occupational dose limit for the lens of the eye?
Answer: 15 rem (150 mSv)
10 CFR 20.1201 sets the annual occupational dose limit for the lens of the eye at 15 rem (150 mSv).
The ALARA principle in radiological protection stands for:
Answer: As Low As Reasonably Achievable
ALARA stands for 'As Low As Reasonably Achievable,' requiring doses be kept below regulatory limits using reasonable means.
According to ICRP recommendations, what tissue weighting factor (wT) is assigned to the gonads?
Answer: 0.12
ICRP Publication 103 assigns a tissue weighting factor of 0.08 to the gonads; the value 0.12 applies to the colon, lung, stomach, and breast.
Which NRC regulation establishes radiation protection programs for nuclear power plants?
Answer: 10 CFR Part 20
10 CFR Part 20 establishes standards for protection against radiation applicable to all NRC licensees, including nuclear power plants.
The concept of 'committed effective dose equivalent' (CEDE) accounts for radiation dose from:
Answer: Internal radionuclide intake integrated over 50 years
CEDE is the effective dose equivalent from internally deposited radionuclides, integrated over a 50-year period following intake.
Under DOE Order 458.1, the public dose limit for DOE operations is:
Answer: 100 mrem/year
DOE Order 458.1 sets the public dose limit at 100 mrem/year (1 mSv/year) for members of the public from DOE operations.
Which of the following best describes the 'stochastic' effects of radiation?
Answer: Effects whose probability increases with dose but severity does not depend on dose
Stochastic effects such as cancer have a probability that increases with dose but the severity (e.g., a tumor) is not dose-dependent once they occur.
