Rb sr dating problems

Most readers appreciate the hard science, but many have struggled with the equations.The purpose of this series is to demonstrate in no uncertain terms that these dating methods do not prove that Earth is millions or billions of years old, as is often reported.

This allows rubidium to readily substitute for potassium in all K-bearing minerals.

Determining the half-life of Rb presents scientists with a challenge for two reasons.

First is the extremely long half-life of Rb, and second is because Rb beta decays with a relatively small energy of 275 ke V.

The potassium-argon dating method—once heralded as a solid scientific method—has proven to be unreliable.

______________ sing rubidium (Rb) decay as a clock to date minerals was first suggested by Otto Hahn and Ernst Walling in 1938.
