Chlorine 36 (³⁶Cl, T_1/2 = 0.301 Myr) is one of the long-lived radionuclides that are difficult to measure by accelerator mass spectrometry due to contamination with the interfering isobaric ³⁶S. Anthropogenic ³⁶Cl is mainly produced by the neutron capture reaction ³⁵Cl(n, gamma)³⁶Cl. In this presentation, we report on the progress of the detection technique of anthropogenic ³⁶Cl using the 6 MV AMS system and its possible application to the investigation of radioactive materials in nuclear facilities and the estimation of neutron integral doses.
