The small ball in the center is plutonium. The outer shells both hemispheres are lead. The lead reflects neutrons back in.
Opened up radiation poors out. Fully closed… it goes critical and gives off a shot load more. When doing experiments/lab tests, they would occasionally cover it up with spacers… or a screwdriver blade….
The screwdriver was more common because it was “convenient”- but more than a few times the hemisphere slipped off and flashed the research with lethal radiation.
This, is why it’s nicknamed a “demon core”- it’s killed more than a few people working with it
Can someone explain this to me?
To add to what rogue said…

It’s a plutonium sphere, was used for testing shapes to determine criticality(sustained nuclear chain reaction) in the Manhattan project.
