Scope
This standard specifies the methods and procedures for analyzing and determining the 14C content in biological samples using the oxygen bomb combustion method. This standard is applicable to the analysis of the 14C content in biological samples such as agricultural and livestock products, aquatic products, and herbal plants. The detection limit of this method is 10 Bq/kgC (absorption method) and 30 Bq/kgC (suspension method).
