Has anybody heard of a product called "Leadite"? It's supposed to be a concrete cmu block-like unit that contains lead used for radiation shielding. I've searched this site and the web using google to no avail. Thanks in advance.

OK, I've discovered part of my problem - it's spelled "ledite" and it's manufacturered by Atomic International. So now my question is does anyone have any experience with this product?

They are small interlocking units that weigh-in around 290 lbs/cu.ft. The advantage is that they require less thickness than CIP concrete for the same relative neutron sheilding capability. Another manufacturer is NELCO, which is listed under Section 13090 - Radiation Protection on 4-Specs.

Isn't this thread supposed to be in the MasterFormat area? Oops - I thought you said "Luddite"!

I"ve used the lead containing blocks -- they go up like anything else. There is another option, though, of blocks that contain boron, which are lighter weight but seem to provide the same shielding capacity. If you have a shielding specialist on the project ask them about it. I've used the Nelco products. Obviously, the big issue is that they weigh a lot... and the building has to handle that. They are also harder to handle (by a person) on the project site because of their weight.
