Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. Potassium-Argon (K-Ar) dating is the most widely applied technique of radiometric dating. In fact, this form of dating has been used to date the age of rocks brought back to Earth from the moon.

Potassium occurs naturally as three isotopes.The radioactive potassium-40 decays by two modes, by beta decay to 40 Ca and by electron capture to 40 Ar. There is also a tiny fraction of the decay to 40 Ar that occurs by positron emission.The calcium pathway is not often used for dating since there is such an abundance of calcium-40 in minerals, but there are some special cases where it is useful.

Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar). Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.

You also have potassium-- and once again writing the K and the 19 are a little bit redundant-- you also have potassium-41. So this would have 22 neutrons. 22 plus 19 is 41. This accounts for about 6.7% of the potassium on the planet. And then you have a very scarce isotope of potassium called potassium-40. Potassium-40 clearly has 21 neutrons.
