-Since everything is regulated these days up to the point that only multi-national-companies can obtain the stuff they need to develop something it's quite a challenge to find sources to test your Geiger Counter with more than just the local dose rate. +Since everything is over-regulated these days, up to the point where only multi-national-corporations can obtain the resources needed to develop something easily, it's quite a challenge to find radioactive test sources to probe a Geiger Counter with more than just the local dose rate. So instead of having simple access to quality test-radiators which can be handled and stored in a safe manner, we have to improvise and hack something out of whatever we can find. When we consider that the regulation's original intent has to protect of people from harm, it backfired pretty well.
