Yes I'm serious! I started an education to be a hospital-physicsian, and have practised such as it. But I had to quit, because I "got insane", and was taken in on the mental-hospital :undecided:. (Yes it's true), but now I'm pretty healthy.
But my interest in radiation, is still there!

Don't do it, you'll just end up with a bunch of radioactive crap everywhere + radiation sickness. The man built no reactor of any kind, just a big mess.
