Radiation Hazard
This equipment generates X-radiation at levels that
can be lethal. This unit must only be operated by
personnel that are certified and experienced in
industrial x-ray generation. All operators must also
understand the characteristics of radiation and the
associated dangers of exposure to primary,
secondary, and residual sources of radiation.
Lethal Voltages
High power radiation sources depend upon the
generation of extremely high, yet well-protected
voltages. Under no circumstances should the
operator access the interior of the Tube Head.
Under no circumstances should the operator
access the interior of the Control Unit or the Cooling
Unit except for the procedures outlined in Section 5
of this manual.
Badges
All personnel who work around X-ray equipment
must wear a functional exposure dosage indicator.
Radiation Protection
X-ray equipment must be operated within properly
designated protective barriers. Otherwise,
personnel must not approach closer than 100 feet
from the Tube head, and in no cases cross the
direct path of the primary beam.
Radiation Monitoring
After installation, re-installation, transporting,
performing maintenance, and during all
radiographic operations not within a radiation
enclosure, a radiation survey should be
performed.
Warm-Up Procedures
Explicit procedures are outlined for
“running-up”
high voltage with new equipment, equipment with a
new tube, equipment that has been inactive for a
period of time, and for daily use. These procedures
must be strictly followed at all times.
Operation
Equipment must be operated at correct
source voltage and frequency, and must
never be left running unattended. The gas
pressure in the Tube head must be checked
to ensure it is within allowable limits before
operating the unit. Never operate this
apparatus if output voltage/current is unstable.
Cooling Unit Operation
Regularly check the coolant solution in the Cooling
Unit to ensure:
◆
the coolant level is within specification
◆
the pump circulates the coolant properly
◆
the fittings, hoses, and coolant reservoir does
not leak
Always allow the Cooling Unit, or the fan on air-
cooled units, to run approximately 5 minutes after
completion of x-ray generation.
Caution:
Cooling unit shipped without
coolant. Cooling unit must be
filled to the appropriate level
prior to operation.
Care in Handling
Extreme care must be taken when handling
this x-ray apparatus. Exercise caution when
packing, unpacking, shipping, and while
performing maintenance. Remember, the X-
ray tube is durable but breakable: be sure to
store and ship it in the upright position.
