Chapter 25, Problem 90SAE

Interpretation Introduction

Interpretation:

The half life of a given nuclide is 1.91 years. The decay constant is to be calculated.

Concept introduction:

In nuclear reaction, one subatomic particle is bombarded on an atom and decay of parent nuclide starts. Each of the radioactive elements has a definite half life period and decay constant which can be calculated from the formula $t_{\frac{1}{2}}=\frac{0.693}{\lambda }$

$an{d}^{}\lambda =\left(\frac{0.693}{t}\right)\log \left(\frac{N_0}{N_1}\right)$.
