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 )

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.

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.

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.

Let T be the mean life of a radioactive sample. 75% of the active nuclei present in th sample initially will deacy in time

A radionuclide with half life T is produced in a reactor at a constnat rate p nuclei per second. During each decay, energy E_(0) is released. If production of radionuclide is started at t=0, calculate (a) rate of release of energy as a function of time (b) total energy released upto time t
