Activity of
Duration
Formula used:
Graph of count rate versus time is as below:
We know that
While
Thus, total number of counts=
Hence, ratio of counts at t=0
Where,
For 131I
Where,
Decay activity of a solution is plotted on graph, by plotting count rate per second over a period of 16 days; we get a curve of total activity as a function of time.
The equation of the curve is a summation of activities of two components
Equation of curve of activity versus time is:
Conclusion:
We calculate the relation count rates over a period of 16 days for
And the corresponding equation of curve obtained by plotting counting rates per second over a period of 16 days is:
The equation is the addition of activities of
