The most common isotope of uranium 2U has a half-life of 4.47 x 10 years, decaying to 92 234 Th by a emission. i) iv) Write down the nuclear decay equation. What is meant by the decay constant? Calculate the mass of uranium would be required for an activity of 6.00 μCi. Calculate the number of a particle emitted per second by 30.0 g of uranium. [1 Ci= 3.70 x 10¹⁰ decays/s]
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.
