protection) for subsequent entry into and decontamination of the above area.
f.
Using reference material and given the activity, calculate radiation levels from a
point, line, and plane source.
g.
Given buildup factors and half value layers, perform shielding calculations.
h.
Using reference material and given a scenario including bioassay results, isotopic
and chemical form etc., calculate the internal dose to be assigned to an individual.
7.
Radiation protection personnel shall demonstrate a working level knowledge of
as-low-as-reasonably-achievable (ALARA) principles, and their application to
radiological work activities.
Supporting Knowledge and/or Skills
a.
Describe the various components of an effective ALARA program including
operations, engineering, and management controls.
b.
Describe how optimization techniques, including cost-benefit analysis, are used in
the ALARA process.
c.
Discuss the essential elements of the job planning process and the post-job ALARA
review for work performed in a radiation or radioactive contamination area.
d.
Describe the various radiological performance indicators that are applicable to the
ALARA process.
e.
Calculate person-rem estimates and use the results in ALARA cost-benefit analysis.
f.
Discuss methods to minimize Total Effective Dose Equivalent (TEDE) by evaluating
the trade-offs in considering the internal and external dose components.
g.
Using knowledge of ALARA principles, discuss how to perform an evaluation of a
radiation job plan and the associated worker job performance.
8.
Radiation protection personnel shall demonstrate a working level knowledge of
the application of engineered radiological controls and facility design, including
containment/confinement systems.
Supporting Knowledge and/or Skills
a.
