Carbon dating non organic materials intimidating your boss
There are two very destructive steps in radiocarbon dating as it is now practiced.
( 1) Pre-cleaning to rid organic artifacts of the commonly occurring humic acid and carbonate/oxalate contaminants are accomplished by serial strong acid, strong base, and strong acid treatments.
So, if there are no other means by which to absolutely date materials, it is still possible to work out a sequence of events.
Carbon dating works by basing an age calculation on the ratio of radioactive carbon (C) in the atmosphere before nuclear bomb testing to the same ratio in the sample. Using a formula that compares that ratio to a standard modern ratio produces a “percent modern carbon” (p MC) value that scientists use to estimate carbon ages for carbon-containing materials.
Carbon-14 (C at levels detectable by modern instruments.[i] Carbon dating of historical objects of known age is sometimes accurate back to about 1,000 BC, as verified by historical records.[ii] Carbon-14 dating begins with sound, repeatable science when researchers record isotope ratios.
Dendrochronology, or counting tree rings, is particularly useful for logs preserved in fairly recent sites and that can be compared to known historic trees.
[Originally posted as Carbon-14 Dating and Biblical History] Carbon dating assigns ages to once-living materials such as wood, bone, teeth, and shells.
