== Lead Bricks ==

5/11/21

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.

== 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".
