Best suited to the carbon 14 dating technique

This is then transformed into isotopic ratios and then used to date the material.The machinery you use has to be tuned and calibrated to which isotopes you want to measure and needs to be set with the correct running conditions.The age we come up with is around 50 000 years old.The reason it isn't 1 million year old is because the half-life of 14-C is about 5 730 years, which means after about 50 000 years there is no more 14-C to measure, hence the limit of that dating technique is about 50 000 years.Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.This low concentration will mean your counting statistics will not be as robust and may result in decreased precision.Another limitation is the length of time a decay series can be used for.

So you can never have perfect running conditions and certain parameters will change over time, this is just the nature of high-tech machinery.The limitations of radiometric dating can be split into two general categories, analytical limitations and natural limitations.Analytical limitations encompass the limitations of the machinery that is being used to date a material.Natural limitations encompass those as a result of nature.For example, you may want to date the same zircon crystals using the U-Pb method.

Another example, you may want to use (carbon-14) to date an old object.
