A patient with prostate cancer is treated with implanted seeds that contain the samarium isotope 153Sm which decays with a half-life of 1.9 days by emitting beta particles (RBE=1) each of 0.8 MeV energy. The seeds have an activity of 100 MBq when first implanted, and 40% of the decay energy is absorbed by the 0.024 kg prostate gland. What dose equivalent does the gland receive after 1.9 days?
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.
