Although the beta particles given off by different radioactive materials vary in energy, most beta particles can be stopped by a few millimeters of aluminium.

WebAlpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom, which consists of … Web14 jun. 2024 · It is commonly taught that alpha particles have high ionising ability and low penetrating ability (explained by saying due to their large charge and kinetic energy, they are able to knock off electrons of atoms during a collision). However, what I do not understand is why do gamma radiation does not have a high ionising ability.
