The physical half-life of 113m/n (Indium isotope) is 1.7 hours. The init sample has 1.07×1016 atoms and a mass of 2 pg. 113m/n atoms remain after four hours? a) How p) What is the activity of this sampie at t = 4 hours? =) Specific activity is defined as the activity per unit mass of a radioa sample. What is the specific activity of the 113m|n sample after 4 many
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.

113m
a) How many
In atoms remain after four hours?
b) What is the activity of this sampie at t = 4 hours?
c) Specific activity is defined as the activity per unit mass of a radioactive
sample. What is the specific activity of the 113mIn sample after 4 hours?
d) Enough 113min must be obtained at 4 P.M. Thursday to provide 300 kBq at 1
P.M. Friday. How much 113mIn should be obtained?
