Question
Chapter 25, Problem 63IAE
Interpretation Introduction
Interpretation:
The half-life of 137Cs radioisotope produced during Chernobyl accident is to be calculated.
Concept introduction:
Half-life means the time taken to disintegrate half of the atoms of a radioactivematerial. It is related to the decay constant of the radioactive molecule as follows:
This is because all the radioactive decays follow the first order kinetics.
It can be micro sec for some molecules, while it can be years for some other molecules.
