What methods are used to detect radiation?

Answer 1

Because ionizing radiation does just that, ionizes, it is easy to see that using a medium like a gas, and a voltage, you can measure the amount of charge liberated in that medium. That is the most common method of measuring radiation. The infamous Geiger Counter is in reality a small volume of gas, with a voltage applied across it. As the radiation enters the gas, it causes electrons to be formed, which are collected and measured to determine the amount of initial radiation present. Another common detection device uses a process similar to the Glow-In-The-Dark plastics, paints, and watches that can be found in every store. While a little more complicated than that, the processes used with radiation detection is called scintillation. Scintillation is the giving off of visible light after interaction with radiation. The light can be collected then and used as another measure of the radiation intensity and energy. But, there are many different ways of measuring radiation, using semiconductors, liquids, superheated bubbles, crystals and plastics..
