WebJul 6, 2024 · Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays. Alpha particles are the least dangerous in terms of external exposure. Each particle contains a pair of neutrons and a pair of protons. They don’t penetrate very deeply into the skin, if at all — in fact, clothing can stop alpha particles. WebThe idea to get across here is that the alpha particles, in comparison with beta particles, are massive and carry double the charge. This means that they are much more likely to interact with air molecules as they pass through air causing ionisation. The ionisation process is often described in terms of the alpha particle knocking an electron ...
