f.
Notify Radiological Control personnel.
D. 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:
1.
Prevention
A sound maintenance program can prevent many radioactive material releases.
a.
Establish a solid routine maintenance program for operating systems to minimize failures
and leaks that lead to contamination.
b.
Repair leaks as soon as identified to prevent a more serious problem.
c.
Establish adequate work controls before starting jobs.
d.
During pre-job briefings, discuss measures that will help reduce or prevent
contamination spread. The agreed upon measures should be implemented by workers at
the job site.
e.
Change protective gear (e.g., gloves) as necessary (typically as directed by Radiological
Control personnel) to prevent cross-contamination.
f.
Stage areas to prevent contamination spread from work activities.
1)
Cover work area to minimize cleanup afterward.
2)
Cover piping/equipment below a work area to prevent dripping contamination onto
cleaner areas.
3)
Cap contaminated pipes or systems when not in use.
g.
Prepare tools and equipment to prevent contamination.
1)
Bag or sleeve hoses and lines to prevent contamination.
2)
Minimize the equipment and tools taken into and out of contamination areas.
3)
Cover/tape tools or equipment used during the job to minimize decontamination
after the job (i.e., taping up a screwdriver before use).
h.
Use good housekeeping practices; clean up during and after jobs.
"Good Housekeeping" is a prime factor in an effective contamination control program.
Each radiological worker should keep his/her work area neat and clean to control the
spread of contamination.
