[Just Duke]

Can anybody identify these?

I think they are 25 lb ingots.

Sure are. Just don't want to melt them down if they a sail boat ballast or aircraft ballast. I am a radionucleid phoebe.

Drive around the airport with 'em and see if they set off any alarms.

Man I don't even want to go over to the guys house and pick them up now. lol

Buy a geigercounter not that expensive, and checking old clay pottery from certain parts of the worl is rather "INTERESTING", as are antique coleman sock mantles...just a few things I was showed when I went to troxler nuclear density certification.

They are indeed ballast for a boat. I have also seen them used in processing equipment that has a need for mass dampening, though a lot of machines use a single large block of granite. Don't know about their use in aviation.

They look like they came fron N.T.S., They should be lead.

Be carefull Dye

Nevada Test Site for those that don't reside here. Guess I'll stick with WW's.

They look just like the lead bricks I saw around Sandia Labs in Albuquerque.

Sandia & Los Alamos Labs use the bricks for radiation shielding and doorstops.[smilie=1:

What does the guy want for them?

If Coleman mantles were a newly introduced product they would require a minimum of 3' of air space around them by 1987 law. [that is the last year I heard them discussed in Haz-mat]. What is messed up the fact that they are grandfathered or the current regulations? Gianni

Las Vegas has a good dept. Take one to the fire department and ask 'em to put the meter on it. They can tell you right quick whether or not they're "hot"

[RU shooter]

I didnt think lead was able to be contaminated with radiation? If it did what good would it be as radioactive shielding.

[Just Duke]

I read somewhere here that they use some sort of an isotope to make sail boat keels.

[Lloyd Smale]

put some gloves on and a mask to handle them and place them in a box and address it to me. I will do alot of testing on them and tell you 25 years from now if i die from it.

I am all for this as well. I will gladly take them off of your hands. I have a friend of mine from OK who posts is a member of our fine community, and he uses lead that come from a hospital's x-ray shielding. IIRC it came in bricks like that. I honestly would not worry about them being hot. If I remember correctly Lead will not form a radio active isotope due to the number of valence electrons it has. That is why it makes perfect radiation shielding. If I could get them at a reasonable price (preferably free) I would take them.

The bricks pictured are Radio Active Containment room bricks, they are certified as close to pure lead as can be. They contain traces of other elements such as silver, very small amounts that is near impossible to remove.
They are marked with numbers stamped on them stating the weight.
They came in around 25# and 50# bricks.
There were also smaller 1# or so ingots that were used as, "mortar".

If there are no melted edges they are unused.

Lead will not absorb radioactive emissions. Lead its self is decomposed uranium.


I have a supply, and wish I could come up with more.

They are not cast, they are extruded, you can see the marks going length wise on them.

[uncle joe]

i'm with lloyd and Joe
lets split them up :mrgreen:

duke take one of those bricks and put one lb of tin in it ,cast some 45's for your new vaqueros. put 5gr of clays or 6 gr titegroup in the cases and go shoot them.

I am aware of that. Again I just didn't want to end up with a HOT isotopic sail boat keel weight. My secondary concern was some yahoo melted a bunch of wheel weights down and these be chocked full of ZINC.

[Just Duke]

Here you go guys.


Aircraft ballast.....Hmmmm. Well, I am an Aircraft Mechanic [and millwright] operating around Houston Texas and when we have to balance the control surfaces on 737s, 727s, etc (flaps, alerons, elevators, etc) we use the Boeing approved material. [Same with MacDonald-Douglas craft] Spent Uranium. Slightly heaver then lead but with aprox same melting point. Usually each piece is coated with white epoxy paint when it is already weighted and for a particular location, but the custom large pieces for aircraft balance (like in the nose or tail cone) come in big slabs, unpainted. It too comes in various shapes like you describe

By the way, lots of spent U235 is also used in sailboat keels because it is heavier. My old boats keel had been cast of lead reactor shield bricks, not spent U but it still had a slightly higher count than regular lead.

But, living in Denver exposes you to a higher anual dose of radiation then the spent U235. A frequent flyer receives a LOT of rads at altitude so your risk is not too high. EXCEPT YOU SHOULD BE EXTRA CAREFULL NOT TO BREATH THE FUMES FROM MOLTEN U !!!!!!!!!!!!!

Like Salsa, just watch what you got, ....nuf said

Well.... I smelt up a bunch of XrayRoom lead and have been around a LOT of Rads in my time... so I'm another one who wouldn't mind a gift from the Flat Rate Box Fairy... :mrgreen:

Hey Ironside. :-D

[Just Duke]

I guess I will just leave them at the guys house. He probably won't sell them for what I want to pay for them anyway. Thanks all for your input. :drinks:
