2)
Be familiar with radiological conditions in the area.
3)
During work delays, move to lower dose rate areas.
4)
Use remote handling devices when possible.
5)
(Insert facility-specific information.)
c. Proper uses of shielding
Shielding reduces the amount of radiation dose to the worker. Different materials
shield a worker from the different types of radiation.
1)
Take advantage of permanent shielding, such as non-radiological
equipment/structures.
2)
Use shielded containments when available.
3)
applicable.
4)
Temporary shielding (e.g., lead or concrete blocks) can only be installed when
proper procedures are used.
5)
Temporary shielding will be marked or labeled with wording such as
"Temporary Shielding - Do Not Remove Without Permission from
Radiological Control."
6)
Once temporary shielding is installed, it cannot be removed without proper
authorization.
When evaluating the use of shielding, the estimated dose saved is
compared to the estimated dose incurred during shield installation and
removal.
7)
(Insert facility-specific information.)
d. Source Reduction
Source reduction is another method of reducing radiation doses. Source reduction
often involves procedures such as flushing radioactive systems, decontamination,
and removal of contaminated items. This is done to reduce the amount of
radioactive materials present in/on a system because these materials can add to
radiation levels in an area.
