RE: How a Ukrainian Geiger Counter works: Teardown/Explanation
Really interesting, and great original work. Presumably you would need a different design of detector to pick up Alpha and Beta radiation?

For beta, you just need a tube that doesn't absorb all of the beta radiation in the walls of the tube before it can ionize the internal gas. Semiconductor detectors are somewhat good for beta since they don't have to be made with metal walls. This particular tube, the SBM-20, is entirely metal, and as such I expect it would have problems picking up all but the highest energy beta radiation.
As for alpha, you need a specially designed tube. Some I've seen use very thin mica windows to allow alphas into the tube for detection.
I guess the GM-tube is good enough to grab alpha, beta and gamma particles?
btw really nice post ! I like your radioactive posts (as well as the youtube channel bionerd23 XD) and no matter its in any formats :DD
