Is α-decay same as nuclear fission?
What is the difference?
What is the difference?
α-decay is a type of radioactive decay in which an atom releases an α-particle (helium nucleus) from its nucleus. This process reduces the atomic number by 2 and the atomic mass by 4.
α-decay occurs when an atom has an unstable nucleus due to an excess of protons or neutrons. The nucleus then emits an α-particle in order to become more stable.
The main difference between α-decay and β-decay is the type of particle emitted from the nucleus. In α-decay, an α-particle is released, while in β-decay, a β-particle (electron or positron) is emitted.
α-decay plays a crucial role in nuclear reactions, as it is responsible for the conversion of heavy radioactive elements into more stable and less radioactive elements. This process also releases a significant amount of energy.
Yes, α-decay has several practical applications, such as in smoke detectors and nuclear power plants. It is also used in certain medical procedures, such as radioisotope therapy for cancer treatment.
