1.2.4 X-Ray Safety Guidelines
Always follow these X-ray safety guidelines.
1. Do not tamper with the X-ray housing.
2. Do not place the hands between the X-ray source and the
detector when the X-ray is turned on.
3. The information on the labels that are affixed to the system
is very important. Always follow this safety information
explicitly.
4. If you have questions about safety or operation of the
FT-170/CI, contact filtec.
1.2.5 How filtec Measures X-Ray Radiation
This section tells you how filtec measures the gamma radiation
emitted by the FT-170/CI.
• All measurements are taken with Technical Associates Model
Pug-1 survey meter cross-calibrated against an air ionization
chamber survey meter whose response was corrected against
an Americium-241 test source.
• Disable - The radiation levels are not measurable.
• Enable - The extent of the main X-ray beam is completely
contained within the tunnel formed by the inspection head
and shielding bar. All radiation levels outside the main beam
are less than 0.05 mR/HR.
• The system has an optional safety input to disable the X-ray.
The normal inputs used are safety door interlock, or conveyor
run or any other safety item.
1.2.6 Restarting the X-Ray Generator
1. Turn the X-ray on/off switch on.
2. Start the production line if it is not currently running
Result: The red warning light turns on, the auto enable
activates the generator, and the generator begins emitting
the inspection beam.
The FT-170/CI is now ready to resume case inspection.
