Radiocarbon dating problem solving

Note that although carbon-14 dating receives a lot of attention, since it can give information about the relatively recent past, it is rarely used in geology (and almost never used to date fossils).Carbon-14 decays almost completely within 100,000 years of the organism dying, and many fossils and rock strata are hundreds of times older than that.

This activity was selected for the On the Cutting Edge Exemplary Teaching Collection Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories.Radiometric dating — through processes similar to those outlined in the example problem above — frequently reveals that rocks, fossils, etc.are very much older than the approximately 6,000 to 10,000 years reckoned by young earth creationists.The key is to measure an isotope that has had time to decay a measurable amount, but not so much as to only leave a trace remaining.

The half-life , specific to each nuclide, can be accurately measured on a pure sample, and is known to be independent of the chemical composition of the sample, temperature and pressure.

This leaves out important information which would tell you how precise is the dating result.

Carbon-14 dating has an interesting limitation in that the ratio of regular carbon to carbon-14 in the air is not constant and therefore any date must be calibrated using dendrochronology.
