Given:
Half-life of 32 source, days
Time, days month
Here, the selling rate of a radioactive isotope is decided by its activity.
Selling rate = Activity of the radioactive isotope after 1 month
Initial activity, disintegration/sec
Disintegration constant is given by
Activity (A) is given by
Here, Disintegration constant
Activity of the radioactive isotope after one month (selling rate of the radioactive isotope) (A) is given below .
