How are C and U dating used together in order to determine fossil ages? | Socratic
The half-life of the decay of 14C to nitrogen is years so the concentration halves every years. A practical limit for accurate dating is 26, years (in. Carbon 14 and Uranium are not used together to determine fossil ages. The limitations of radiometric dating can be split into two general Analytical limitations encompass the limitations of the machinery that is.

What are some of the limits of radiometric dating techniques?
This question requires a very extensive answer to be able to cover all bases here but I'm going to attempt to explain the salient facts. Jump down to summary if you just want to know what both categories of limitations are.
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. This technique bombards the sample, slowly drawing material out and then sending it through to an ion counter. 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.
Think of it as making a roast dinner, you're going to need to set the oven at the correct temperature and leave it for the right amount of time to achieve the best results. So you can never have perfect running conditions and certain parameters will change over time, this is just the nature of high-tech machinery.
A small shift in a parameter can affect your final outcome. So some analytical limitations can be the beam intensity, counting statistics, dead-time and so on. These are parameters you can control and will affect how accurate and precise your age-dating is. Don't worry what those parameters mean, just understand they are machine-based.
