Abstract

Long-lived chlorine, ³⁶Cl (T_1/2 = 301,000 y) in environmental samples has been measured by the AMS system installed in Tandem Accelerator Center, University of Tsukuba. A tri-carbon-molecular ¹²C₃^- pilot beam method is used to stabilize the terminal voltage of the tandem. A small amount of pure carbon graphite is well mixed into a AgCl target material for creating Cl^- and ¹²C₃^- in the ion source. A ³⁶S isobaric interference in the system is eliminated to determine ³⁶Cl in environmental samples by chemical procedure. Some samples containing chlorine such as soil, chemical reagents and table salt have been collected in the JCO criticality accident site and analyzed to detect neutron-induced ³⁶Cl. The experimental result has been compared with a theoretical calculation.
