Also, since the time of Chernobyl and Fukushima, you could develop a baseline for the amount of Caesium in an organism and compare daughter products as a proxy, because Caesium has a relatively short half-life, that makes it perfect for dating something happening after these nuclear events that happened only a few decades or a few years ago.

    I just turned a different environmental disaster into a proxy dating mechanism, at least for dating things which are relatively young. Returners, That's not how carbon dating works. Carbon 14 is created from nitrogen in the atmosphere getting hit by protons from the sun. What makes carbon 14 dating useful is that over the detectable time frame of its half life, the nitrogen levels in our atmosphere have remained relatively constant, which in turn creates a constant stream of radioactive carbon which is then taken up by various chemical processes, as you are made from the world around you.
