Chapter 20, Problem 20.24P

Interpretation Introduction

Interpretation:

The time required for the radiation treatment to go if $\text{2}\text{.2}\times {\text{ 10}}^{\text{11}}$ disintegration of $\text{C}\text{o}$ are required to give a dose of 1.0 rad should be determined.

Concept introduction:

The nuclear reactions are a type of chemical process which leads to the formation of some new nuclei with the emission of certain particles. Usually, alpha or beta particles or gamma rays are emitted as a side product with some new daughter nuclei. The nuclei which show spontaneous decay with time are known as radioactive nuclei. The radioactive decay follows the first-order kinetic and the half-life is inversely proportional to the decay constant of the radioactive decay.
