LEAK TESTING
Unless specified otherwise by your license, the gauge must be leak
tested at intervals not exceeding 12 months to ensure the integrity of
the radioactive source encapsulation. Sample analysis must be
performed by a licensed laboratory only.
Using the Troxler Model 3880 Leak Test Kit and accompanying
instructions, perform the following procedure:
NOTE
Ensure that the source rod is in the SAFE position (see
Figure 3-2).
✓
Write the date, gauge model number, and serial number on the
wipe disk.
✓
Remove the control panel from the gauge topshell. Locate the
yellow radiation label on the top surface of the base.
✓
Place two drops of leak test solution on the wipe disk.
✓
Holding the wipe disk with the tongs, wipe the radiation label.
✓
Turn the gauge on its side and locate the opening where the
source rod extends through the gauge base.
✓
Holding the wipe disk with tongs, wipe the area around and
inside the opening where the source rod extends from the gauge
base.
✓
Pack the disk, as instructed, in the envelope and mail to Troxler
Electronic Laboratories, Inc. for analysis.
✓
Secure the gauge properly.
