  3. 19 de out. de 2023 · The Demon core is a 6.2 kg Plutonium-Gallium sphere with a diameter of 8.9 cm (smaller than a basketball). The Plutonium-239 isotope used in the core is a manmade element produced in nuclear reactors. It is highly unstable, radioactive, and decays by emitting alpha particles, which is damaging to our tissues.

  7. 3 de abr. de 2021 · New protocols meant an end to 'hands on' criticality experiments, with scientists forced to use remote control machinery to manipulate radioactive cores at a distance of hundreds of metres. They also stopped calling the plutonium core 'Rufus'. From then on, it was known only as the 'demon core'.
