outdated Arista Pro 400

I hope that if I build a photo freezer, that I can land such a good deal! You are certainly one of the exceptions I mentioned in my post. Blocking 99% of gammas with 3/4-inch of lightweight material is certainly amazing...but probably out of reach for most of us.

Dear 2f/2f;
In the 1980s there was a firm in Maryland that sold material and plans for home bomb shelters and they mentioned foam lead sheeting for radiation protection was available from them and many years later a friend of mine found a similar but thinner material, 1/4 in at a military surplus store near Berkley, Ca for $200 a yard and he bought 4 yards for his freezer and for an air travel film case. He told me that the Xray machines at airports couldn't see through it so they made him open it himself and they hand inspected the contents, which was what he wanted in the first place. I believe it may have been surplus from Lawrence Labs or one of the defense contractors in the area.
