    Who measures uranium in pounds? I feel like if you’re not using metric you probably shouldn’t be handling uranium.

    GOD DAMNIT! Who touched my Uranium-235?? I left it RIGHT HERE where this lead is.

    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.
