Cs-137 is distributed primarily by rainfall, and is readily absorbed by soil. Cesium-137 decays to barium-137 which then decays to a non-radioactive form of barium. Cs-137 has a half-life of 30.17 years. ... Applications of Caesium-137 in Soil Erosion and Sedimentation Studies (an introduction). Department of Geography, University of Exeter.

Cesium-137, stejně jako ostatní izotopy cesia, reaguje s vodou za vzniku rozpustného hydroxidu cesného. Cesium má podobné biologické vlastnosti jako draslík a rubidium. Jakmile se dostane do organismu, tak se více či méně distribuuje po celém těle, přičemž nejvyšší koncentrace jsou v …

Cesium-137, a by-product of nuclear testing, was used to date sections of reservoir sediment from the core. Age-dating of core sediments was done by analysis of their cesium-137 content. Cesium-137 is a by-product of nuclear weapons testing. It first occurred …
