In order to evaluate the production of ³⁶Cl, which becomes an issue during the decommissioning of high-energy accelerator facilities, irradiation experiment was conducted on power cables using secondary neutrons generated by bombarding a copper target with a 24GeV/c proton beam at the CERN/CHARM facility. After irradiation, AMS was used to quantify ³⁶Cl in the sheath samples. The thermal neutron flux estimated from the ³⁵Cl/³⁶Cl ratio was higher than previous study obtained with gold foil activation detectors, suggesting an influence due to differences in shielding conditions.
