There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry. Gas proportional counting is a conventional radiometric dating technique that counts the beta particles emitted by a given sample.There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry

How do you test for carbon-14?

Wipe surveys using liquid scintillation counting is the preferred method for detecting C-14. Most G-M detectors are not likely to detect the presence of C-14 in amounts less than about 100,000 dpm (0.05 µCi).

How long does carbon dating test take?

Typically, about 1 � 3 days of counting time is required. In spite of many uncertainties, this method gives fairly good idea about the age of the sample up to about 60000 years.
