Use of Caesium-137 technique for the assessment of soil

137 Cs is a product of atmospheric nuclear testing, which commenced in the 1950s. 137 Cs strongly adheres to soil particles and therefore can be used as a tracer in soil movement studies.

T3DB Cesium-137

Cesium is the chemical element with the symbol Cs and atomic number 55. Cesium-137 is a radioactive isotope of cesium with a half-life of 30.07 years. It is produced from the detonation of nuclear weapons and is produced in nuclear power plants. Cesium-137 was released to the atmosphere most notably from the 1986 Chernobyl meltdown.

Cesium and Rubidium Statistics and Information usgs.gov

Cesium, the most electropositive and least abundant of the five naturally occurring alkali metals, was discovered spectroscopically in 1860. The first cesium metal was produced in 1881. Because cesium is not mined domestically, the United States is completely dependent on imports. Historically, the most important use for cesium has been in research and development,

Cesium-137, on the other hand, has a half life of 33 years. And plutonium has a half life of 24,000 years. Because all radionuclides decay over time, and because most radionuclides are bound in sediments, simply leaving a contaminated reservoir alone may be the least ecologically disruptive and most cost- effective cleanup strategy.
