5DX Main Cabinet Radiation Integrity Check
—
To verify the 5DX Cabinet Integrity and
containment of X-Ray emissions, perform the
following steps:
CAUTION If any of the readings in the following tests exceed 0.15
mRems/hour, shut off the X-ray system and contact SPT
second level support immediately.
a. Turn ON the GM Radiation Meter (Victoreen™
Model 290 or equivalent). Allow a warm up period
of 2 minutes.
b. From the DOS prompt type
hvxray -s
and press
Enter
.
c. At the hvxray menu use the arrow keys to select
“Cathode µA” and press Enter , then type
10
and
press Enter. This will bring current to 10
microamps so X-rays are on slightly.
d. Use the GM Meter and perform a quick survey of
the 5DX Main Cabinet. Focus on areas where
radiation leaks are suspect such as doors, access
panels, etc.
Leakage must be less than 0.15
mRems/hr.
e. Increase the Cathode µA and to
40
(using the same
process as in b and c above) and press
Enter.
f. Use the GM Meter and perform another quick
survey of the 5DX Main Cabinet.
Leakage must be
less than 0.15 mRems/hr.
g. Increase the Cathode µA and to
100
and press
Enter.
