PROBLEM TO BE SOLVED: To highly sensitively measure tritium in a state in which radon, thoron, their progeny nuclides, and other background nuclides are absent in carrier gases, reduce carrier-gas consumption, eliminate the need for waste disposal work, and reduce maintenance work. SOLUTION: A tritium monitor comprises a sampling means for sampling a gas to be measured; a water vapor separation means 5 for separating water vapor from a sample gas and discharging it into a carrier gas; a sample water collection means 9 for collecting sample water from the carrier gas containing water vapor; a tritium detection means 21 for detecting tritium of the collected sample water; and a tritium measuring means 25 for inputting signals acquired by detecting tritium and measuring tritium.
