Chapter 18, Problem 22E

Interpretation Introduction

Interpretation:

The age of the artifact, when carbon $\text{-14}$ radioactivity of an ancient wooden artifact is $6.25\%$ that of a reference sample is to be estimated.

Concept introduction:

For all the radioactive samples, the level of radioactivity decreases with time. For the activity of the sample, the amount of time that is required to reduce it by half is known as the half life. The half-life is represented by the symbol $t_{1/2}$.
