stick to the use of nuclear fission. Nuclear power today is a developing and important technology‚ and despite its environmental setbacks‚ it remains a source a strong source of power. In the early 20th century‚ radioactive elements such as radium were being discovered. Also‚ Einstein had devised the mass-energy equivalence principle. This led to people start pursuing the generation of electricity from these elements and in accordance with the principle of mass-energy equivalence. However‚
