The aforementioned steps are carried out, but an additional course of is launched which relies on neutron irradiation from a nuclear reactor to transform 39K (stable) into 39Ar (unstable). A normal reference materials of known age is irradiated concurrently the unknown samples, making it attainable to make use of a single measurement of argon isotopes to calculate the 40K/40Ar ratio and obtain an age.
