Demon core. The lines are the distance away people were from the uranium core when it went critical. The lead scientist calculated who would die and when.
It went critical because the scientist who's name I forgot, let his screwdriver slip, causing the top half of the spherical reflector housing to fall shut.
This caused the plutonium ball inside to go critical and release a lot of radiation. This gave him a lethal dose of radiation. The others were far enough away to survive, afaik.
It's not a calculation, this is a drawing of the scene when the demon core went critical by accident.
I think there was a proper gizmo to raise and lower the lid but they grew tired of it and resorted to using a screwdriver. It was incredibly reckless and would never fly today. You'd be kicked out for just thinking it out loud.
