Laboratory for liquid scintillation counting

The laboratory for liquid scintillation counting is responsible for the measurement of the radioactivity due to low-energetic beta emitters (such as tritium, radiocarbon, phosphorus-32, nickel-63, technetium-99, etc) in both environmental and biological samples (water samples, fish, urine samples, wipes, etc). A liquid scintillation counter is used where the detector (a liquid scintillation cocktail) is mixed with the sample to be measured. Measurement of liquid samples requires little preparation, reason why this technique is suitable for rapid determination of radioactivity.

A dedicated laboratory for sample preparation holds the various distillation setups, the combustion installation for the analysis of organically bound tritium and radiocarbon and the installation to extract radiocarbon (as 14CO2 ) for absorption in CarboSorb or trimerisation into 14C-benzene. A separate counting room provides the four liquid scintillations counters.
