    Out of curiosity and for strictly not-remotely-nefarious reasons, how expensive would a megagram be?

    I assume they just bought Ike, a centimeter cube of the stuff. (Which is a common thing for this kind of collector. Most solids come in centimeter cubes if they’re not particularly spicy.)

      1Mg @ 19.8g/cc

      1000000/19.8=50505cc

      ³√50505 = 37cm

      So a little bigger than a cubic foot assuming you could prevent super-criticality somehow

        Based on the Wikipedia article, it’s $6,490,000/kg.

        Assuming you can legally purchase that amount (which you can’t), you could even find that much for sale (would you probably couldn’t), and the price didn’t go up as you purchased more of a very scarce resource (which it would), it would be about $6.5 billion US.

        Cool, though I would assume the supercritical point would be a lot higher for Pu-242. I can’t imagine that anyone would have knowingly sold this kid a fissile isotope.

      A cubic centimeter is ~150th of a modern nuclear weapon’s core. U-235 production accounts for every single gram, plutonium is even stricter.
