Potassium-40 (40 K) is a radioactive isotope of potassium which has a long half-life of 1.25 billion years. It makes up about 0.012% (120 ppm ) of the total amount of potassium found in nature. Potassium-40 undergoes three types of radioactive decay .

19 K) has 25 known isotopes from 34 K to 57 K as well as 31 K, as well as an unconfirmed report of 59 K. [3] Three of those isotopes occur naturally: the two stable forms 39 K (93.3%) and 41 K (6.7%), and a very long-lived radioisotope 40 K (0.012%) Naturally occurring radioactive 40 K decays with a half-life of 1.248×10 9 years. 89% of those ...
40 K occurs in natural potassium (and thus in some commercial salt substitutes) in sufficient quantity that large bags of those substitutes can be used as a radioactive source for classroom demonstrations. 40 K is the radioisotope with the largest abundance in the human body. In healthy animals and people, 40
A banana contains naturally occurring radioactive material in the form of potassium-40.. Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana.

The 40 K / 39 K ratio in nature is constant so the 40 K is rarely measured directly, but is assumed to be 0.0117% of the total potassium. Unless some other process is active at the time of cooling, this is a very good assumption for terrestrial samples. [5] The radiogenic argon measured in a sample was produced by in situ decay of 40 K
Potassium–calcium dating, abbreviated K–Ca dating, is a radiometric dating method used in geochronology. It is based upon measuring the ratio of a parent isotope of potassium (40 K) to a daughter isotope of calcium (40 Ca). [1] This form of radioactive decay is accomplished through beta decay. Calcium is common in many minerals, with 40
