Principles and use of radiological instrumentation and radiological monitoring/survey practices

DOE-STD-1174-2003

Supporting Knowledge and/or Skills

Describe the effects of radiation exposure on the cellular level including:

Direct effects

Indirect effects

Describe the factors affecting radiation sensitivity of cells (i.e., The Law of Bergonie

and Tribondeau).

Describe the acute effects and corresponding doses associated with the following:

Blood changes

Hemopoietic syndrome

Gastrointestinal syndrome

Central nervous system syndrome

Discuss delayed effects of radiation exposure including:

Genetic effects

Prenatal developmental effects

Cataracts

Discuss how the Linear Non-threshold Theory is used in developing risk estimates

and dose limits associated with exposure to radiation. (The use of International

Commission on Radiological Protection (ICRP) Publications 26 and 60 or National

Council on Radiation Protection and Measurements (NCRP) Report No. 116 may be

helpful).

Radiation Protection personnel shall demonstrate a working level knowledge of

the principles and use of radiological instrumentation and radiological

monitoring/survey practices.

Supporting Knowledge and Skills:

Describe the principle of operation of gas-filled detectors.

Discuss the following for gas-filled detectors:

Voltage-response curve (i.e., six region curve)

The three regions useful for radiation detection and measurement

The sequence of events that occur following an initial ionizing event in an

Ionization Chamber, a Proportional Counter and a Geiger-Mueller Detector

Describe the principles of operation of scintillation and solid state detectors.

Describe the principle of operation and application of nuclear spectroscopy.

Discuss the purpose, principles of detection and operation, and field application of

the following:

Continuous air monitors (CAM)

Airborne radioactivity samplers
