Interpretation Introduction

Interpretation:

The activity of a radioisotope is 3000 counts per minute at one time and 2736 counts per minute 48 hours later.  The half-life of the radioisotope has to be calculated.

Concept Introduction:

The emission of elementary particles by atoms is known as radioactivity.  The relation between radioactivity and half-life is:

    ln(AAo)=-ktA-activity at time 't'.Ao-initial activityk-decay constant

Half-life is given by the equation,

    t1/2=0.693kk-decay constant
