Upon attempting to lower Pail 211 into their tile hole, CNL encountered issues with the pail getting stuck. They shipped the pail back to TRIUMF and requested we perform an investigation. The investigation report is attached.

The pail contents must be re-packaged into a new pail.

Note: the F-308 is currently sitting in the Meson Hall warm cell at approximately 250 uSv/h at 0.5 m.

Dose for primary worker (Chad Fisher) who inspected the cable, unbolted the flask lid, and handled the pail briefly: approx. 104 uSv

Dose for secondary worker (Danka Krsmanovic) who swiped the pail and flask to check for contamination: approx. 70 uSv
