Chapter 24, Problem 76A

Interpretation Introduction

Interpretation:

The graph about the method of reducing the effects of radiation exposure needs to be explained.

Concept introduction:

A variety of sources constantly bombard the human body with radiation.

Answer to Problem 76A

The intensity of radiation is inversely proportional to the square of the distance.

Explanation of Solution

The graph represent that the more the distance away from the source, the intensity drops as a power function.

Since, relation between I and d is $\text{I}\propto \frac{1}{{\text{d}}^{\text{2}}}$

In hyperbolic equation,

$\text{y}\propto \frac{1}{{\text{x}}^{\text{2}}}$

If,

$\begin{array}{c}\text{y}=\text{I}\\ {\text{x}}^2={\text{d}}^{\text{2}}\end{array}$

If distance increases from the source of radiation, the intensity of radiation decreases exponentially.

Conclusion

The best way to get less intensity of radiation is just move away from the source.
