At `t= 0`,a sample of radionuclide A has the same decay rate as a sample of radionuclide B has at `t = 60` min. The disintegration constants of A and B are `lambda_(A)` and `lambda_(B)` respectively, with `lambda_(A) lt lambda_(B)`.

At t=0, a sample of radionuclide A has the same decay rate as a sample of radionuclide B has at t=30min. The disintegration constants are lambda_(A) and lambda_(B) , with lambda_(A)ltlambda_(B) . Will the two samples ever have (simultaneously) the same decay rate?
