Interpretation Introduction

Interpretation: Sample of radon gas representation is given, best representation of the system after about 10 days from the options should be found out.

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.
• Half-life ( ${\text{t}}_{\frac{\text{1}}{\text{2}}}$) is the time required for a quantity to reduce to half its initial value.
• Radon is a major indoor pollutant and it is a colorless, odorless, and tasteless gas that enters a building through tiny cracks in the basement floor.
