³⁶Cl is a beta-emitting nuclide with a long half-life, and typical radiochemical analysis requires complex separation procedures and advanced techniques. In order to safely and smoothly bury disposal of radioactive waste containing ³⁶Cl, a rapid analysis method for ³⁶Cl is required. In this study, a rapid analysis method for ³⁶Cl by ICP-MS/MS for metal waste was investigated and its applicability to actual waste was evaluated.
