Chapter 20, Problem 86RQ

Interpretation Introduction

Interpretation:

The amount of dose received by the worker from the given radioactive source for the same period of time is to be calculated.

Concept Introduction:

The inverse square law states that the intensity of the radiation is directly proportional to the inverse of the square of the distance. It is stated as follows:

$\frac{I_1}{I_2}=\frac{d_2{}^2}{d_1{}^2}$

Here, $I_1$ is intensity at distance $d_1$, and $I_2$ is the intensity at distance $d_2$
