Interpretation: Date of detonation of first atomic bomb is given. Percentage of strontium
Concept introduction: A process through which an unstable nuclide loses its energy due to excess of protons or neutrons is known as radioactive decay. Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second. Half-life of radioactive sample is defined as the time required for the number of nuclides to reach half of the original value.
To determine: Percentage of strontium
