Paint some of them gold, and list them on e-bay

My father-in-law just had to have one of the ingots I made. It is now painted gold, lacquered and sitting on his desk.

Even better, I used a lyman ingot mold. Father-in-laws name? Lyman!
 
I talked to someone I know that works in radiation:

Most hospitals by "moly generators" that have a small glass column inside of a lead shield. You can run some nitric acid through the column and 'milk' Technetium-99 which is used for nuclear med studies. 99 times out of a 100, the hospitals return the unused generators to the vendor, because they still contain some residual rad materials. It would be possible to collect the generators, store them until all the rad materials decays away, then extract the lead. Molybdenum 99 has a fairly short halflife (~60 hours) which decays to Technetium-99 which has a half life of ~6 hours.
 
Alloy Purity

Those things are supposed to of a known purity (something like 98% I believe) to insure they stop all those vigorous rays. I used to have a huge supply of the smaller containers the isotopes were transported in, and they were all nearly pure lead. I used 50-50 bar solder to alloy it but I can't imagine what it costs now. Muzzle loaders (and fishermen) didn't need to, but if you're shooting anything but 38s with 2.7 BE, you need some hardener. Right before I left Alamogordo NM (Holloman AFB) to move here to Sumter (Shaw AFB) I saw 2 5-gallon bucket of wheel weights in a mechanics shop, and asked if I could have some. He gave me the whole enchilada, and helped me put it in my truck. I had to unload it piece meal, but I still have 4 or 5 50 cal ammo cans full in the shop after 8 or 9 years. It must be the old stuff because when I cast with it they are relatively hard. I try to do all my casting in the fall/winter, for obvious reasons. I'll go on a casting binge for a week or two and do up enough for most of the year. Right now, all the casting stuff is put up ;)
