Radiometric dating rock types

That is, the analysis of the isotopic and chemical composition of the sample has far greater uncertainty than any uncertainty in the decay rate itself.

The energy locked in the nucleus is enormous, but cannot be released easily.For these reasons, if a rock strata contains zircon, running a uranium-lead test on a zircon sample will produce a radiometric dating result that is less dependent on the initial quantity problem.Another assumption is that the rate of decay is constant over long periods of time.The effect of this on alpha decay, which is the most common decay mode in radiometric dating, is utterly insignificant.There is another effect that takes place in the "electron capture" type of Beta decay.
