Potassium radioactivity
WebPotassium-Argon Dating Ancient rocks contain trapped argon gas as a result of the decay of the radioactive isotope of potassium-40 This happens when a potassium nucleus captures an inner shell electron, also known as electron capture 40K + e– → 40Ar + ve The potassium isotope can also decay by β – emission to form calcium-40 40K → 40Ca + β– + vₑ WebPotassium 40 makes the ocean very radioactive. There are 10,000 units of potassium for every unit of caesium in the ocean, even after Fukushima.” In fact, there is so much potassium in the ocean, and it decays over such a long period of time, that in oceanographic processes this radiation is almost a constant.
