Discussion on the LS method can be broken down into a number of topics : counting liquid, counting vials, and the LSC method, including counting instrumentation and potential problems associated with measurement of beta (ß)-decay by LS counting.
In the majority of LSC facilities, the scintillation solvent is benzene (C), before being catalytically trimerised to benzene.
This contamination usually comes from the burial environment, but can also come from such things as post-excavation conservation practices.
Pretreatment follows a mixture of physical and chemical processes.
Benzene synthesis procedures vary considerably in different laboratories.
