Interpretation Introduction

Interpretation:

The age of the Earth, the assumptions involved in the calculation of this age, and whether the assumptions are valid or not, are to be stated on the basis of $\text{U}-238$ dating techniques.

Concept introduction:

The nuclei which are heavy and unstable undergo the process of decay and lose their counter parts in order to gain stability. This process is known as radioactive decay or radioactivity.

Radioactive decay involves the emission of three types of radiations, known as alpha, beta and gamma radiations.
