Painted half size lead bricks (1"x2"x4") with red epoxy based paint for safer handling when building shielding arrays. Made the mistake of letting them dry on porous surface and now have to find way to remove cardboard that is sealed to the last unpainted side of bricks.
5/27/21
Finished painting lead bricks which need to dry/cure for 24-48hrs
6/1/21
Moved dried/cured painted lead bricks from painting area to clean room
Cleaned each brick with a wet wipe before transition into clean room, will be allowed to air dry on steel table
Lead Sheet
5/17/21 - 5/18/21
Sheared a lead sheet into 6 rough 3"x3" squares to be used for attenuation measurements with NaI detectors
Lead pieces were wiped down with a wet wipe, duct taped, rewiped, and hammered flat.
Thickness of the lead pieces is around 0.055".
