An unstable isotope of cobalt, 60Co, has one more neutron in its nucleus than the stable 59Co and is a beta emitter with a half-life of 5.30 years. This isotope is widely used in medicine. A certain radiation source in a hospital contains 4.20×10−2g of 60Co A) What is the decay constant for that isotope? Express your answer with the appropriate units. B) How many atoms are in the source? C) How many decays occur per second? Express your answer as a number of decays per second. D) What is the activity of the source, in curies? Express your answer in curies.
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.
