Alpha Decay
Alpha decay is a type of nuclear reaction where an unstable atom releases an alpha particle, consisting of two protons and two neutrons (essentially a helium nucleus). This process reduces the original atom’s atomic number by two and its atomic mass by four, transforming it into a new element. Alpha decay often occurs in heavy elements like uranium and radium, helping them achieve greater stability. Although alpha particles cannot penetrate materials well, they can be harmful if ingested or inhaled, as they can cause significant damage to internal tissues at close range.

Alpha decay is a type of radioactive decay in which an unstable atomic nucleus loses energy by emitting an alpha particle. An alpha particle consists of two protons and two neutrons, essentially a helium nucleus. This process reduces the original atom's atomic number by two and its mass number by four, transforming it into a different element. Alpha decay occurs in heavy elements, such as uranium and radium, and is a natural way for these elements to achieve stability. The emitted alpha particles can be harmful if ingested or inhaled, but they have low penetration power and can't pass through skin.
