Abstract
A continuous tritium radioactivity measuring system is disclosed, in which a sample gas containing tritium is mixed with hydrogen gas, water vapor and lower hydrocarbon gases with the assistance of a catalyst for causing an isotope exchange reaction between the tritium contained in the sample gas and hydrogen. The resultant tritium gas and lower hydrocarbons containing tritium are removed from the remaining hydrogen water, and radioactivity detection is performed thereon.
