RE: Shielding Material

Bob,

 

They use a lot of this line of alloy to make blocker trays for linear accelerators and radiation therapy simulators. They usually cast the blocks in Styrofoam molds and heat it in a big coffee urn. (most often used "cerrobend" or "cerrolow" ` 185 degree F. melt point for safety reasons.) Machines well if you don't let it get too hot. Not as nearly as "squishey" as plain lead.

Just a thought. ~4" stops 1meV. Don't know about plating though.

Available at McMaster-Carr (http://mcmaster.com) retailer.

 

Good Luck
