All radioactive decay follow 1st order kinetics and this is where the similarity ends. The rate of radioactive reactions is measured by calculating the rate of change of nuclei of the radioactive substance. For a radioactive decay A ® B, the rate of reaction is calculated as
Integrating the differential rate law we get
log Where No = number of nuclei of A at t = 0
Nt = number of nuclei of A at t = t
l = decay constant
The expression can be rearranged to give
Nt = N0e–lt …(1)
This suggests that the number of nuclei of radioactive substance A at any instant of time can be calculated, by knowing the number of nuclei at t = 0, its decay constant and the time.
Just like a 1st order reaction the half life of radioactive decay is given by
Average life time is defined as the life time of a single isolated nucleus. The life time of a single isolated nucleus is .
