Radioactive dating radiometric east america dating

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.It does not give dates of millions of years and when corrected properly fits well with the biblical flood.There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks.

Anything over about 50,000 years old, should theoretically have no detectable C.It cannot be used to date volcanic rocks, for example.The rate of decay of N in 5,730 years (plus or minus 40 years).These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.The isotope concentrations can be measured very accurately, but isotope concentrations are not dates.
