PROBLEM TO BE SOLVED: To provide a laser-type concentration measurement apparatus for released radioactive materials which can simplify a system and a sampling device, and reduce possibility of exposure to radiation by eliminating off-line working. SOLUTION: The laser-type concentration measurement apparatus for released radioactive materials takes off gasses discharged from a nuclear reactor facilities to the environment, analyzes fluorescence by irradiating a laser light which stimulates a specific wavelength of the radioactive materials, and measures tritium, iodine, and the radioactive materials in noble gases and concentrations thereof.
