Helium and carbon dating
Even with an obvious lack of sample documentation there is other substantial criticism of the accuracy of the findings of the RATE project. For example, the project's final results were an age of 6,000 ± 2,000 years; the standard deviation should have been 6,000 ± 4,600 years (Henke, 2005).
In Figure 2, one sample has been contaminated by gaining some of the parent product, and another sample has been contaminated by losing some of the parent product.
With more of the parent product existing in the rock sample, more of the daughter product will have been created; with less of the parent product existing in the rock sample, less of the daughter product will have developed.
The resulting plotted points should line up near a single sloping line which is then used to calculate the age.
The RATE team has jumped the gun by preparing a radical model like accelerated decay, which would have a wide variety of serious consequences that have not been considered.
Helium isotope and concentration characteristics were determined for a suite of groundwater samples from the Amadeus Basin in Central Australia.
While the RATE project can be commended for trying to use scientific methods for proving a young Earth, there are too many questions regarding its execution and too much ability for a false date to be calculated from the Helium amounts in the rock samples.
