FUN 1 EO: 1.45 & 1.46

1 / 7

Contact dose rates are dose rate measurements taken how?

Through administrative limits for exposure

At least 30 cm from the radiation source or from any surface that radiation penetrates

By conducting a 'General Area Survey'

By placing the radiation detector housing on the surface being measured

2 / 7

What could be the possible consequences if federal dose limits are not maintained?

Reduced efficiency in nuclear reactors

Decreased regulatory oversight by the NRC

Reduction in plant administrative limits

Increased risk of adverse health effects, NRC fines, disciplinary actions, and increased regulatory oversight

3 / 7

A 'General Area Survey' is conducted to establish what?

Contact dose rates on the surface being measured

Contact dose rates at least 30 cm from the radiation source

General area dose rates at least 30 cm from the radiation source

General area dose rates within 10 cm from the radiation source

4 / 7

Which title and part of the Code of Federal Regulations establishes the dose limits for radiation workers?

Title 10, Part 20

Title 30, Part 5

Title 5, Part 30

Title 20, Part 10

5 / 7

What is the importance of documenting general area dose rates?

Establishing stay times for personnel and aiding job planning and establishment of exposure controls

Facilitating the administrative process for workers

Determining the efficiency of nuclear reactors

Increasing the risk of adverse health effects

6 / 7

What is the main purpose of having plant administrative limits for radiation exposure in a commercial nuclear power facility?

To minimize the risk of challenging the legal dose limits set in 10CFR20 and limit exposures to workers

To reduce the need for regulatory oversight by the NRC

To increase the efficiency of nuclear reactors

To facilitate the administrative process for workers

7 / 7

Why are contact dose rates documented?

For establishing expected rates of exposure to the extremities and determining the use of extremity dosimetry

To minimize the risk of challenging the legal dose limits

For imposing NRC fines on the plant

For deriving estimates of whole body exposures
