Cesium-124 of 124Cs is een onstabiele radioactieve isotoop van cesium, een alkalimetaal. De isotoop komt van nature niet op Aarde voor.

Cesium-124 ontstaat onder meer door radioactief verval van barium-124.

[bewerken | brontekst bewerken]

Cesium-124 vervalt door β+-verval naar de isotoop xenon-124:

De halveringstijd bedraagt ongeveer 31 seconden. Xenon-124 is niet helemaal stabiel maar heeft een zeer lange halveringstijd.
