Without the large datasets necessary to provide the statistical basis for calculating quantitative uncertainties, reporting the analytical uncertainty is the only real option.The CRONUS-Earth Project produced datasets appropriate for this assessment.Permission is hereby granted to the author(s) of this abstract to reproduce and distribute it freely, for noncommercial purposes.
Using those datasets, the uncertainty of the chlorine-36 technique was bounded using the Root Mean Square Error (RMSE) of the primary and secondary chlorine-36 datasets, yielding a technique uncertainty between 7.5-20.0%.
The individual production rate uncertainties were calculated using a camel-plot analysis to look at the variation in sample uncertainty with changes in chlorine content.
The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.
Production rate uncertainties for spallation and low-energy neutron pathways were calculated based on the results and yielded a 4% uncertainty for spallation pathways and 20% uncertainty for the low-energy neutron production pathway.
