Safety Inspection

Radiation Enclosure Interlock Test

The enclosure, not the operator's memory, is what keeps a source from exposing the bay. The test is cold: door, lights, beacon, dosimetry dates. Exposing the source is not the test method.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Perform a cold test with the source not exposed
  2. Confirm door interlock, warning lights and beacon operate
  3. Verify dosimetry for assigned personnel is current
  4. Check the enclosure survey records are in date
  5. Do not expose a source under this inspection

Why This PM Exists

The enclosure, not the operator's memory, is what keeps a source from exposing the bay. The test is cold: door, lights, beacon, dosimetry dates. Exposing the source is not the test method.

What Skipping It Looks Like

A defeated door switch gets taped because it nuisance-trips, and the beacon is a lamp nobody notices is dark.

Setting the interval

Monthly cold test. A failed interlock takes the cell out of service until it is repaired, not until the next shot is convenient.
