LPX-200
Industrial Imaging System
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
Tubehead. Also, 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 Tubehead, 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 Tubehead 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.
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.
