Chapter 19, Problem 19.107QP

Interpretation Introduction

Interpretation:

A radioactive isotope with short half-life or with long half-life is more hazardous has to be identified.

Concept Introduction:

Isotope that have unstable nuclei that decomposes are called radioactive isotope.

Radioactive decay is the spontaneous process of breaking down an atomic nucleus by releasing particles and energy.

The decay constant can be calculated by

$\lambda =\frac{0.693}{t_{1/2}}$
