The time-dependent concentration N (t) of a radioactive isotope used to treat cancer patients is given by the equation N(t) = Noe– 0.01t, where t is the time in seconds. What is the activity of the isotope (i.e., the decay rate in disintegrations per second) after 10 minutes if the initial concentration No is 1,000,000?
