Beschreibung
Zusammenfassung:	A continuous measuring system of tritium radioactivity is disclosed, in which a sample gas containing tritium is mixed with hydrogen gas, water vapor and lower hydrocarbon gas with an assistance of a catalyst for causing isotope exchange reaction between tritium contained in the sample gas and hydrogen. Resultant tritium gas and lower hydrocarbon containing tritium are removed from hydrogen water and a radioactivity detection is performed therefor.
