Web7 sep. 2024 · Beta particles are much smaller than alpha particles and therefore, have much less ionizing power (less ability to damage tissue), but their small size gives them much greater penetration power. Most resources say that beta particles can be stopped by a one-quarter inch thick sheet of aluminum. WebThinking about the learning. It is quite common to see statements along the lines of alpha particles are more ionising than beta, but this is not actually the case if both kinds of particle start with the same energy.. Thinking about the teaching. The point to stress here is that the alpha radiation causes ionisation over a shorter path, creating a higher density of …

Web14 dec. 2024 · Beta particles are high-energy, high-speed electrons or positrons emitted by certain fission fragments or by certain primordial radioactive nuclei such as potassium-40. The beta particles are a form of ionizing radiation also known as beta rays. The production of beta particles is termed beta decay.
