Radioactive Emissions

Radioactive emissions are electromagnetic radiations which occur due to the spontaneous disintegration of unstable nuclei. Natural elements with atomic number greater than 83 and isotopes of some lighter elements are found to be radioactive. They are categorized as alpha, beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei , beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and are short electromagnetic waves consisting of high energy…
