Module 9: Radioactive Contamination Control
Instructor's Notes
1.
Personnel decontamination
EO7 Identify the normal
methods used for
a)
Normally accomplished using mild soap and
decontamination.
lukewarm water per radiological control
organization instructions.
b) More aggressive decontamination techniques are
performed under the guidance of the Radiological
Controls Organization.
2.
Equipment and area decontamination
Equipment and area decontamination is the removal of
radioactive materials from tools, equipment, floors, and
other surfaces in the work area.
NOTE: In some situations, decontamination is not
possible.
a.
Economic considerations : Cost of time and labor to
decontaminate the location may outweigh the
hazards of the contamination present.
b.
Radiological conditions: Radiation dose rates or
other radiological conditions may present hazards
which exceed the benefits of decontamination.
The decontamination activity may not be ALARA,
in that it costs, rather than saves personnel dose.
c.
Hazardous conditions: The physical or chemical
conditions in the area may prevent entry for
decontamination purposes.
G. Types of Contamination Areas
EO8 Define Contamination,
High Contamination, and
1.

Areas.

removable contamination levels are, or are likely to
be, greater than the limits specified in 10 CFR 835
