Hi Sci,

What's the logic behind Cesium 137 dating? I was reading about it's use in authenticating vintage wine which was explained thus:

if/then: If it's present in a wine, then the wine was bottled after above ground nuclear testing began in the 1950's. Cesium 137 didn't exist in the environment until those events.

Does this mean all wines (and people?) from 1950ish-present contain Cesium-137?

How is it dispersed in the environment so that some items absorbed it and some did not?

Basically, whats the universal logic statement behind dating items with Cesium 137 and what objects does this apply to?

Does it only exist in people who've lived during a period of Cesium-137 exposure or does it carry forward to all people, nuclear tests forward, until it decays?

It's inheirited. Once its in you're body you're body begins producing it, producing it for the body of a unborn chiled, the chiled's body begins producing it aswel.
