1.2.3 How the FT-170/CI Provides Safety From X-Ray
Radiation

X-Ray Generator On/Off Switch
The X-ray on/off switch is located on top of the inspection head
next to the warning light. This switch deactivates the X-ray
generator regardless of the auto enable/disable status.
The filtec model FT-170/CI system utilizes an X-ray tube to
produce the X-ray radiation required for performing inspection
activities. The secured and insulated X-ray source housing
completely contains and shields all high voltage components
within the X-ray housing assembly.
The X-ray assembly contains a thermal safety sensor that
monitors the temperature of the X-ray housing assembly and
immediately shuts off (de-energizes) the X-ray generator when
the temperature exceeds 60 degree C. When the X-ray generator
is de-energized, no X-ray is produced and there is no residual
X-ray exposure.
The only possible way to be exposed to hazardous levels of
radiation using this equipment is externally, through excessive
exposure to a radiation source outside the body. There are no
by-products that can be ingested into the body.
The FT-170/CI is unlikely to create hazardous radiation levels for
the following reasons:
• The FT-170/CI's X-ray generator produces a relatively weak
source of low energy (low penetrating power) X-ray radiation.
To receive a hazardous dose of radiation from this low energy
source would take extremely long exposure directly to the
main radiation beam.
• While we warn against placing hands or other body parts in
front of the X-ray beam when it is turned on, it would take
several hours of exposure for the hand to receive an excessive
radiation dose.
• The X-ray beam is tightly confined by shields and collimators
and is completely contained within the inspection tunnel.
Because the radiation beam does not spread outside the
inspection tunnel, it is highly unlikely that under normal
circumstances an appreciable radiation dose could be
received at a location other than directly in front of the
activated X-ray beam.
