Define the following terms:

Dose equivalent

Shallow dose equivalent

Deep dose equivalent

Effective dose equivalent

Committed dose equivalent

Committed effective dose equivalent

Total effective dose equivalent

Whole body

Extremity

Lens of the eye dose equivalent

Derived air concentrations (DAC)

Annual limit of intake (ALI)

Quality factor

Weighting factor

Roentgen

Rad

Rem

Sievert

Gray

Stochastic effects

Nonstochastic (deterministic) effects

Describe the various types of bioassays, their applications and limitations.

Discuss the methods of reducing dose from internally deposited radionuclides.

Discuss the process used to evaluate dose based on bioassay results.

Describe the principle of operation, proper use, placement, function, and type of

radiation detected by the following dose-measuring instruments:

Thermoluminescent dosimeter, including Albedo dosimeter

Pocket dosimeter (quartz fiber and electronic)

Film badge

Personnel nuclear accident dosimeter

Discuss the concepts of International Commission on Radiological Protection (ICRP)

Publications 26 and 30 as they relate to internal and external dosimetry.

Discuss the newer concepts of ICRP Publications including; 60, 66, 68, 71, and 72

and DOE Radiological Control Technical Positions (RCTP) papers, such as RCTP

2000-01, as they relate to DOE requirements for internal and external dosimetry.

The RCTPs are available at: http://www.eh.doe.gov/whs/rhmwp/tpp.html

Discuss various methods used to estimate worker exposure in the absence of

individual monitoring results.

Given airborne radioactivity concentration, DAC value and worker occupancy time,

evaluate resulting worker dose.

Radiation protection personnel shall demonstrate a working level knowledge of

the biological effects of radiation.
