Dan, are you suggesting that leached minerals could mimic DU? Such has not
been my experience. In northern New Mexico, we almost always find U234
greater than U238 in water, and also sometimes in irrigated produce.
However, we have never found any evidence of U238 being greater than U234
in leached minerals or in natural biota.
