 Method/Apparatus/Procedure:
   The method described in ref 1 in which tritium oxide acts as a tracer, was used. Air saturated with radioactive water vapor was bubbled through the (1) sample until saturation was attained. Dissolved water was separated from (1) by absorption on calcium oxide. The tritum was transferred in the counter through equilibration with ethanol vapor.
