WebThe rate for radioactive decay is: decay rate = λN with λ = the decay constant for the particular radioisotope The decay constant, λ, which is the same as a rate constant discussed in the kinetics chapter. It is possible to express the decay constant in terms of the half-life, t1/2: λ = ln 2 t 1 / 2 = 0.693 t 1 / 2 or t 1 / 2 = ln 2 λ = 0.693 λ WebCount-rate is the number of decays recorded each second by a detector, such as the Geiger-Muller tube. The illustration below shows how a radioactive sample is decaying over time. From the start...
