  • So I ran the numbers. U-235 decays into Pb-207, which means about 12% of its mass is radiated away in alpha decay. Which sounds like a fuckton.

    Also, it’ll mean that that chunk of lead will be a touch heavier, at 13.2 lbs

    The Maths:

    U-235 decays into Pb-207. To three significant digits, 207/235 = 0.881, equivalent to 88.1%, meaning 11.9% is radiated away.
    88.1% of 15 lbs = 13.2 lbs.








  • Honestly, whatever makes the most sense with the materials in the local area. And then I don’t mean what you can get from the local hardware store, but literally, what the earth in the area provides. If you have lots of clay, then brick would be best. If you have lots of big stones, then stone construction it’ll be. If you’re deep in the woods, then a wooden building would serve you just right. Maybe a combination of materials and techniques if you have options in the area.

    Bonus points if you can build in a way that passively optimises for managing things like moisture and temperature.
