Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.
Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.
date of organic material - but an approximate age, usually within a range of a few years either way.

Applications range from drinking water analyses of radon, food control for 90Sr, radioactive effluent measurements at nuclear power plants, emergency preparedness for nuclear power and homeland security, radiocarbon dating, biofuel and other biobased material analyses.
With both passive and active shielding, in terms of background reduction, QUANTULUS far surpasses the performance of any other liquid scintillation counter.
The naturally occurring concentration of C that was part of the organism when it died is measured.
Therefore, the first task is to effectively pretreat the sample to remove any exogenous carbon that has entered the sample since death, and which might otherwise bias the results.
