The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
Daghlian was irradiated as a result of a criticality accident that occurred when he accidentally dropped a tungsten carbide brick onto a 6.2 kg bomb core made of plutonium–gallium alloy. This core, subsequently nicknamed the "demon core", was later involved in the death of another physicist, Louis Slotin.

The 35-year-old Canadian physicist and Manhattan Project scientist died as the result of an accident while performing an experiment called "tickling the dragon's tail" with a plutonium core which came to be known as the "demon core". His screwdriver slipped, exposing him to a fatal dose of radiation.

OMG—she's darling! Shadow has the perfect name for her jet-black coat, though it also makes me wonder whether she follows her mom around like a shadow, too.
Reactor core temperatures reached 800 °C (1,500 °F), nearly enough to melt the fuel rods, although the crew was able to regain temperature control by using emergency procedures. The incident contaminated parts of the ship, some of the onboard ballistic missiles and the crew, resulting in several fatalities.
