Module 9: Radioactive Contamination Control
Radiological worker response to a spill of

response to a spill of
Each of the examples listed above may be a spill of
radioactive material. Here is the minimum response
to a spill of radioactive material:
Stop or secure the operation causing the spill, if
Warn others in the area.
Isolate the area.
Minimize exposure to radiation and contamination.
Secure unfiltered ventilation.
Notify Radiological Control personnel.
Contamination Control Methods
Every radiological worker should perform work in
such a manner as to minimize the generation of
radioactive contamination and confine the spread of
radioactive contamination to the smallest area
possible. By controlling contamination, the worker
minimizes the potential for internal exposure, and
personnel contamination can be minimized.
Examples of methods used to control the spread of
radioactive contamination follow:
EO4 Identify the methods
used to control radioactive
A sound maintenance program can prevent many
radioactive material releases.
Establish a solid routine maintenance program for
operating systems to minimize failures and leaks
that lead to contamination.
Repair leaks as soon as identified to prevent a more
