We also offer liquid scintillation analysis using an extra low background Quantulus 1220 for high precision measurements on benzene.

Very small samples (less than 300 mg) are analyzed by accelerator mass spectrometry (AMS).

Evidence for Isotopic Fractionation does show up in isotopic data so it is a factor that needs to be considered.

Water flow through rocks is important because all parent substances and many daughter substances are water soluble.

This is particularly important in light of the Biblical flood.

How a rock is formed is important to understanding its isotopic make-up and any dates derived.

Isotopic Fractionation is a physical separation of isotopes and a non-radioactive source of isotope ratios.

It can be caused by heating and cooling, water flow, contact between high and low concentration magma and just normal molecular motion.

Young Earthers point to an infamous dating error as evidence that the Earth is only as old as the Bible says.

Quick cooling or not having contact with the air can affect theoretical mechanisms for "resetting" the clock.

Some times radiometric dating produces impossible results.

However, it is typically unknown and simply assumed whether these ratios of elements are the result of radioactive decay over time or other processes that have taken place in the rock.

Ages of Rocks in Millions of Years Sometimes different methods used on the same rock produce different ages.
