D. LICENSING
TRAINING
Troxler Electronic Laboratories, Inc. continues to provide a one-day
training seminar for nuclear gauge operators and individuals designated as
Radiation Safety Officers. This class provides radiological physics
familiarization and instruction in the safety procedures required to operate
a nuclear gauge. Operators outside the U.S. should contact their Troxler
representative for training and assistance.
LEAK TEST
Unless specified otherwise by your radioactive material license, the gauge
must be leak tested at intervals not exceeding 12 months to ensure the
integrity of the radioactive sources contained in the gauge. First, make sure
the source rod is locked into the storage, or SAFE, position. Using the
Troxler Model 3880 Leak Test Kit and accompanying instructions, remove
the control panel from the gauge front. Looking down into the gauge
interior locate the yellow radiation label in the middle of the gauge base
and on the top of the circuit board. Wipe the yellow label with the wipe
disk, using the tongs to hold the disk. Next, turn the gauge on one side and
locate the opening through which the source rod would protrude when
indexing. Wipe around and into this opening. Pack the disk, as instructed,
in the envelope and mail to Troxler Electronic Laboratories, Inc. for
analysis. Reassemble the gauge and secure properly.
NOTICE TO EMPLOYEES
Figure D–1 on page D–6 is a reduced example of a “NOTICE TO
EMPLOYEES” (supplied by your licensing agency) that must be posted
where employees that use the gauge and others who may enter the gauge
storage area can see it. This notice must also be posted wherever and
whenever temporary gauge storage is necessary (in a trailer on the job site,
etc.). It is not required (or advisable) to post the notice on the outside of
any structure where it may be viewed by the general public.
INCIDENTS
If the gauge is removed from the custody of the licensee (i.e., lost, stolen,
etc.) or physically damaged to the extent that the source or shielding may
be or is compromised (open or danger), the licensee must notify the
licensing agency immediately. Call Troxler or your appointed
representative for further advice or assistance.
