The 13 pages that link to Potassium-40, each with the reason it gives.

• PotassiumBroader topic: Its decay contributes to geological dating and to natural background radiation.

• Alkali metalBroader topic: Its decay supports potassium–argon dating of rocks and minerals.

• Potassium ionBroader topic: Potassium-40 can occur as K⁺ and contributes to natural radioactivity.

• Electron captureBroader topic: Its electron-capture branch produces argon-40 used in geological dating.

• Carbon-14Compared with: It provides a dating alternative for rocks and minerals beyond carbon-14’s range.

• IsobarBroader topic: Its decay produces argon-40 or calcium-40, both isobars.

• Argon–argon datingRelated: Its decay supplies the radiogenic argon-40 measured against irradiation-produced argon-39.

• GeoneutrinoCompared with: Its antineutrinos fall below the energy threshold of common geoneutrino detectors.

• Radiogenic heatBroader topic: Its long-lived decay contributes heat in Earth’s crust and mantle.

• Caesium-137Compared with: It provides a natural-background comparison to caesium-137's artificial origin and much shorter half-life.

• Earth's internal heat budgetBroader topic: Its abundance and decay contribute to estimates of Earth's radiogenic heat.

• K–Ar datingRelated: Its decay supplies the radioactive clock measured in K–Ar dating.

• Primordial nuclideBroader topic: It persists in Earth’s crust and mantle and decays through more than one pathway.
