Controlled recovery essentials:
-
One operator acts; one monitors time and readings; both wear dosimetry.
-
Inspect connectors/couplers end-to-end; correct tight bends before any pullback.
-
After freeing the path, confirm with a dummy run, then verify locked-home by indicator and background meter.
Prevention:
-
Plan the straightest route; protect it from disturbance.
-
Perform a clean dummy run before live shots; cap ends when idle.
-
Retire worn guide tubes/connectors early; maintain a stocked retrieval/shielding kit.
-
Drill the “stuck source” scenario; reinforce Time-Distance-Shielding habits.
Close-out: document doses, file the incident report, conduct root-cause analysis, and brief lessons learned.
