After tritiated steam-vapor was introduced into oxide superconductors (YBCO), radioactive YBCO was measured by Radio-Gas Analyzer Method. In this case, YBCO materials was prepared, then absorption period and temperature of tritium was varied properly. The position of tritium desorption peak was determined experimently. As a result, in absorption at low temperature, longer absorption period resulted in the shift of tritium desorption peaks toward higher temperature. On the other hand, in absorption at high temperature two desorption peaks were found. By analysis of the both, tritium desorption quantity at high temperature is twice as large as that at low temperature.
