ABSTRACT:
A system for continuously monitoring air for the presence of tritiated water vapor comprising: contacting a predetermined mass flow of an air sample with a predetermined flow of a liquid miscible with tritiated water to transfer any tritiated water vapor in the air sample to the liquid; stripping radioactive noble gases from the liquid with a stream of gas; and analyzing the liquid for beta radiation to determine the presence of tritium. In the preferred embodiment of the apparatus an air-liquid contactor, a gas-liquid separator and a stripper are combined into a single unit with a common outlet for the contacted air and stripping gas.
