WebThe process of producing alpha particles is called alpha decay. Although these particles can be absorbed by metal foils and tissue paper, they are highly ionising (i.e. they have sufficient energy to interact with electrons and detach them from atoms). WebIonising radiation deposits a large amount of energy into a small area. In fact, the energy from one ionisation is more than enough energy to disrupt the chemical bond between …

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 …
