Argon dating kalium

Kalium-argon basics . Kalium forekommer i to stabile isotoper (41 K og 39 K) og en radioaktiv isotop (40 K). Kalium-40 henfalder med en halveringstid på 1250 millioner år, hvilket betyder, at halvdelen af 40 K-atomer er væk efter det tidsrum. Dets forfald giver argon-40 og calcium-40 i et forhold på 11 til 89. Potassium-Argon Basics . Potassium occurs in two stable isotopes (41 K and 39 K) and one radioactive isotope (40 K). Potassium-40 decays with a half-life of 1250 million years, meaning that half of the 40 K atoms are gone after that span of time. Its decay yields argon-40 and calcium-40 in a ratio of 11 to 89.
