Are they stupid at PM or just selling misinformation?

an hour agoThis matches other sources on the internet: a bomb requires about 15kg of U-235 [0] with a good use of neutron reflectors, and HEU by definition contains 20%+ of U-235 [1]. We don't know exactly what the U-235 concentration was in the Kodak device, but reasonable values would make the claim "roughly" correct.
