11.9 Standard Sources SA-1, SA-8
11.9.1 ON/OFF mechanism: To test the ON/OFF
mechanism, move the handle back and forth
several times between the ON and a OFF
positions. The handle should always move freely.
There may be some slight resistance to movement
due to bearing friction.
Do not force the handle.
If a portable radiation survey meter is available, the
radiation field intensity can be measured at points
around the detector housing.
11.9.2 Wiping the test point: Anyone following
the instructions of a leak test kit may perform the
wiping procedure, but only a person or company
specifically licensed by the NRC or an agreement
state may do the analysis for radioactive material.
Using a cotton swab, wipe around the rotor shaft on
the top of the source holder and at all seams, as
shown in Figure 6. These areas are most likely to
be contaminated if the source leaks. Do not touch
the cotton-tipped end or allow it to touch other
objects, as this would spread contamination if a
leak is present.
After making the wipe test, replace the cotton swab
in the vial with the cotton-tipped end at the bottom.
Replace the cap on the vial, place the vial in the
shipping tube and replace the top on the shipping
tube. Send to: Ronan Engineering Company,
8050 Production Drive, Florence, KY 41042.
11.10 Mandatory Reporting
Loss, theft or transfer of this device and failure of or
damage to the shielding or the source containment,
must be reported to the NRC or an agreement
state.
In addition to notifying the NRC or the agreement
state agency, Ronan Engineering should also be
notified, so that proper help can be provided.
If the gage is involved in a fire or explosion, the
area around the gage should be barricaded or
roped-off until the situation can be evaluated by a
specifically licensed person. Telephone Ronan
Engineering at (606) 342-8500.
