- Removed blank off from t2 m9 port, had to pry off with screw driver via spring ears. Clean removal it seems.

- Blank off is 200 uSv @ .5 m, 5000 CPM above bg.

- looks like 2 knife steps all around with oozing on the left and right, 0 and 180 deg positions. 0 and 180 look like 2.5 steps. Looks like it took one turn to remove/loosen blank off.

- Junk indium at bottom of exit port still present, indium knife edge seems clean. Ribbon stayed in blank off.
