Answer:
The
given decay sequence is
At any time t, suppose 38S has N1 (t)
active nuclei and 38CI have N2 (t) active nuclei.
= rate of formation of 38CI
and = net rate of
decay of
Multiplying both sides by and
rearranging,
Integrating both sides, we get
?(i)
Where C is constant of integration.
At
Putting in (i), w get
For
maximum count; N2 =max,
or
Or or
