Spent Fuel Bundle Neutron Joke

Text on the meme

Hey /k/, I've recently acquired a source of neutrons. Do you know drillbits have the most cobalt in them? I'm working on a technical project. Pic related, a spent fuel bundle. Also: how much blood is still a healthy amount of blood to pee?

What it means

A photo shows a tall spent nuclear fuel bundle standing in the corner of a room. The poster jokingly claims to have acquired a neutron source and asks about cobalt in drill bits, then abruptly asks how much blood in urine is healthy. The punchline is the absurd escalation from nuclear engineering talk to a horrifying medical question, making it a reaction meme for dangerously unhinged or alarming situations.
