Chapter 21, Problem 6SAQ

Interpretation Introduction

Interpretation:

To find out is a beta emitter with a half-life of 44.5 days.

Concept Introduction:

The time take for the material to reduce into half from the initial value is known as Half-life period. In nuclear physics, how fast the unstable atoms undergo and also it deals with how long the atoms survive. It is also used to denote exponential and non-exponential decay.

The half life can be shown as

$t_{\frac{1}{2}}=\frac{0.693}{k}$

K is decay constant
