WebThe "gun" method is roughly how the Little Boy weapon, which was detonated over Hiroshima, worked, using uranium-235 as its fissile material. In the Little Boy design, the U-235 "bullet" had a mass of around 86 pounds (39 kg), and it was 7 inches (17.8 cm) long, with a diameter of 6.25 inches (15.9 cm). WebNatural uranium consists of a mixture of mostly U-238 (half life 4.5 billion years) and 0.72% of U-235 (half-life 700 million years, therefore considerably more radioactive than U-238).
