WebPotassium is found in most rock-forming minerals, the half-life of its radioactive isotope potassium-40 is such that measurable quantities of argon (daughter) have accumulated in potassium-bearing minerals of nearly all ages, and the amounts of potassium and argon isotopes can be measured accurately, even in very small quantities. 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 ...

"WebIn radioactive decay, a parent isotope decays to a daughter isotope. A number of different isotopes undergo serial transformations (decays). When this happens in the case of a very long-lived parent and a short-lived daughter, an equilibrium condition called secular equilibrium develops after about 6 to 7 daughter half-lives.
