Find the decay constant of `.^(55)Co` radio nuclide if its activity is known to decrease `4%` per hour. The decay product is non-radioactive.

The mean life time of a radionuclide, if the activity decrease by 4% for every 1 h , would b e(product is non-radioactive, i.e., stable )

(a) Assume that a particular nucleus, in a radioactive sample, has a probability rho of decaying in the interval t to t+Deltat . Taking that the nucleus actually does not decay in the above interval, what is probability that it will decay in the interval t +Deltat to t+2Deltat ? (b) Find the mean life of .^(55)C_(0) is its activity is known to decreases 4% per hour. ln((25)/(24))=0.04 .

The half life of a radio nuclide is 77 days then its decay constant is
