Radiation Survey after Installation
1.
Complete the survey sheets with measurements at 30 cm (12") omni-
directionally to record the radiation pattern.
2.
Survey in the closed (OFF) position and then in the open (ON) position.
3.
Do an occupancy evaluation to determine the dose personnel might
receive. There are two categories, each with a different limit:
•
Members of the general public can receive 20 mSv/hr (2 mrem/hr), not to
exceed 1,000 µSv/yr (100 mrem/year). These numbers include only
individuals who are in the area infrequently and have no assigned
reason for exposure.
•
Occupationally-exposed individuals can receive 50,000 mSv (5,000 mrem)
per year with no specified rate limit. This number includes anyone whose
assigned duties require his presence in the vicinity of the source holder.
Complete the evaluation to determine if the limit of 50,000 mSv (5,000
mrem) per year, which would require monitoring, is potentially reachable.
4.
Decide if additional shielding is required to prohibit members of the general
public from receiving radiation doses greater than 20 mSv/hr (2 mrem/hr).
5.
Notify appropriate personnel of the presence of radioactive materials and
precautions that they must take to minimize exposure.
6.
If there are radiation fields above 20 mSv/hr (2 mrem/hr) present on the
detector side, notify the RSO (Radiation Safety Officer) of the problem.
7.
Restrict the area, if required.
Shutter Operation Test (on applicable source holders)
The shutter operation test verifies that the shutter is functioning.
If the shutter does not work correctly, see the
Radiation Safety
