Chapter 17, Problem 95E

Interpretation Introduction

Interpretation: The percentage of total exposure of a person living in high-radon area is to be determined.

Concept Introduction: Radon is a colorless, tasteless, radioactive noble gas that occurs in nature as a decay product of radium.

Radon is responsible for excessive exposure of public to ionizing radiation.

The relation used to calculate the percentage exposure due to radon is expressed as:

$\text{Percentage exposure due to}\text{Rn}=\frac{\text{Radiation exposure}\text{from Rn}}{\text{Total exposure}}\text{×100\%}$

The unit rem is used for human radiation exposure.
