Detection of Alpha Radiation – Alpha Particle Detector - Nuclear Power

WebJul 1, 2024 · Vocabulary. Alpha decay - A common mode of radioactive decay in which a nucleus emits an alpha particle (a helium-4 nucleus). Beta decay - A common mode of radioactive decay in which a nucleus emits beta particles. The daughter nucleus will have a higher atomic number than the original nucleus. WebAlpha particle. If the nucleus has too few neutrons, it will emit a ‘package’ of two protons and two neutrons called an alpha particle. An alpha particle is also a Helium-4 nucleus, so it is ... WebThe alpha radiation ionises the air within the metal chamber. A low electric voltage applied across the chamber causes a current to flow through the ionised air. When smoke particles enter the chamber, the current flow is altered and this in turn triggers an alarm. china springs weather
