Problem 3 – Consider a 210Po (209.982848 u) nucleus that undergoes a decay resulting in 20 Pb (205.974440 u). The mass of an a particle is (4.002603 u). The half-life of Po is 140 days. a) Find the amount of energy released in this radioactive process. b) Find the decay constant of 210P0. 84 c) Consider now a sample of 20Po. Find the amount of time that has passed when only ten percent of the original amount of Po in the sample remain.
Nuclear Fusion
Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fusion is the energy source of the sun and stars.
Fusion Bomb
A fusion bomb is also known as a thermonuclear bomb or hydrogen bomb which releases a large amount of explosive energy during a nuclear chain reaction when the lighter nuclei in it, combine to form heavier nuclei, and a large amount of radiation is released. It is an uncontrolled, self-sustaining nuclear chain reaction where isotopes of hydrogen combine under very high temperature to form helium. They work on the principle of operation of atomic fusion. The isotopes of Hydrogen are deuterium and tritium, where they combine their masses and have greater mass than the product nuclei, get heated at high temperatures, and releases energy.
