The isotope 145Pr decays by emission of beta particles with an energy of 1.80MeV each. Suppose a person swallowed, by accident, 5.0mg of Pr having a specific activity (activity per gram) of 140 Bq/g. What would be the absorbed does from 145Pr in units of Gy and rad over a period of 11 minutes? Assume all of the beta particles are absorbed by the person's body and the person weighs 70 kg.
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.
