Radiometric Dating Uranium and Thorium With time, Thorium 230 accumulates in the sample through radiometric decay. The uranium and thorium decay systems offer a multitude of radiometric dating options. Uranium 238 decays through a series of steps to Lead 206.

About Us The sample age is based on the difference between the initial ratio of U with the environment (i.e., that it is a closed system.) The method is used for samples that can retain Uranium and Thorium, such as carbonate sediments, bones and teeth. Dating Process Be Irresistible + Know What Men Secretly Want!
