Chapter 11, Problem 11.77CP

Interpretation Introduction

Interpretation:

The activity after $\text{24}\text{hours}$ has to be calculated.

Concept introduction:

Half-life:

The time required to reduce a radioactive isotope to half of its initial value.

For non-integral number:

For a non-integral number of half-lives, the fraction of radioisotope remaining is

$\text{fraction}\text{remaining=}{\left(\text{0}\text{.5}\right)}^{\text{n}}$
