Nuclear radiations, i.e WebSome gamma particles interact with the tube wall and knock electrons into the tube gas, where they are detected. This effect enhances the detection efficiency of the gamma particles. You can do a quick check by doubling and tripling the distance between the source and the axis of the Geiger-Muller tube and seeing if the count follows an inverse square …

WebWhy are alpha particles good Ionisers? The Alpha Ionizer is a device used to neutralize static charge on any material. It uses a radioactive source called Polonium (Po-210) to produce ions (positively or negatively charged particles) in the surrounding air. These ions attract their counterparts in order to neutralize the charge on the material. WebIonising radiation comes in three varieties: α (alpha) particles. β (beta) particles. γ (gamma) rays. All of these forms of radiation are energetic enough to pull electrons away from atoms. The atoms that have had electrons removed in this way are now charged particles, or ions, and hence the name ionising radiation.
