5 Commissioning the Source Holder
5.1 Commission the Source Holder
Depending on the source holder type and the specific license requirements, the
process of commissioning the source holder can include:
• Inspecting the mounting supports
• Testing the source holder for any source material leakage
• Conducting open and closed radiation surveys
• Performing an occupancy evaluation
Commissioning Call Checklist
In many installations, a VEGA Americas Field Service Engineer commissions the
gauge. To reduce service time and costs, use this checklist to ensure the gauge is
ready for commissioning before the engineer arrives:
• Allow access to the source holder for testing purposes.
• Have process ready for adjustment.
• To ensure the most accurate measurement, a process adjustment is
necessary. This adjustment requires establishing and changing vessel levels.
If process material is not available, you may use water in most cases.
• Do not remove the lock on the source holder.
• Notify your Radiation Safety Officer or contact VEGA Americas Field
Service if there is damage to the source holder.
Commissioning a source holder is performed only by a specific
licensed individual trained in radiation safety.
See the Radiation Safety Manual for specific details.
