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. 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). cara menghitung margin of error
