Chapter 25, Problem 53A

Interpretation Introduction

Interpretation:

It is to be explained why X-rays and radiation emitted by radioisotopes are called ionizing radiation.

Concept introduction:

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Answer to Problem 53A

Ionizing radiation is radiation having enough energy to knock electrons off some atoms of the bombarded substance to produce ions.

Explanation of Solution

The radiation emitted by radioisotopes and X-rays is known as ionizing radiation because this type of radiation has enough energy to knock electrons off atoms of the bombarded compound and in this process, ions are produced.

This radiation can’t be detected by the eyes, nose, or hands, and people must use detection devices for this purpose, so they can be alerted to the presence of harmful radiation.
