Nuclear reactions are used to generate electricity on Earth as well as in space.
Roughly 13% of the electricity generated worldwide comes from nuclear power plants, though the percentage varies from one country to the next. The use of nuclear energy for power generation and the disposal of nuclear wastes from power plants, as well as concerns about nuclear weaponry, are controversial social and political issues. It is imperative, therefore, that as a citizen with a stake in these matters, you have some understanding of nuclear reactions and the uses of radioactive substances.
Nuclear chemistry is the study of nuclear reactions, with an emphasis on their uses and their effects on biological systems. Nuclear chemistry affects our lives in many ways, particularly in energy and medical applications. Radioactivity is also used to help determine the mechanisms of chemical reactions, to trace the movement of atoms in biological systems and the environment, and to date historical artifacts. Different isotopes of the same element can undergo very different nuclear reactions, and one of our goals in this chapter is to gain a deeper appreciation for the differences among different radioactive isotopes and the ways in which they undergo decay and other nuclear transformations.
In this research, we will try to know how can the enormous nuclear power be transferred to useful power in our daily life.
