HDR Source Exchanges / Record exchange

Record HDR Source Exchange QA

Full QA workflow: source receipt + ODH acceptance checks, chamber constancy on the prior source, new source calibration, timer + survey + summary. Pass/fail is auto-computed against the editable tolerances at the bottom.

No well chambers in inventory. Add at least one in Well Chambers first; the chamber drop-down is empty until you do.

The shortest dwell-time row is the leakage / zero point. Per-row % deviation is computed against the mean of the other rows' net currents (leave-one-out, matching the spreadsheet).
