As we learn

Radioactivity -

A=-\frac{dN}{dt}

- wherein

Activity is measured in terms of disintegration per second

Its SI unit is 'Becquerel'

 

 N=N_{0}\cdot e^{-\lambda t}

N_{Y}=N_{0}\left ( 1- e^{-\lambda t} \right )

Rate of formation of Y is

\frac{dN}{dt}=+\lambda N_{0} e^{-\lambda t}

Which decreases exponentially with time.
