Chapter 20, Problem 20.56QP

Interpretation Introduction

Interpretation:

It should be listed the factors that affect the intensity of radiations from the radioactive element.

Concept Introduction:

• An unstable nucleus emits radiation spontaneously to become stable nuclei by losing energy. This process of emission of radiation by unstable nuclei is known as radioactive decay.
• These emitted radiations may be alpha radiations( $\text{α}$), beta radiations( $\text{β}$) or gamma radiations( $\text{γ}$)
• These unstable nuclei are the nuclei with more than 83 protons and which do not lie within the belt of stability and they are called radioactive element.
