The continuous release of gaseous radionuclides from nuclear facilities such as power reactors, contains trace amount of isotopes of argon, krypton, and xenon. A real-time monitoring spectrometer, consisting of a mechanically-cooled HPGe detector with portable electronics, was setup in field to quantitatively measure the gamma rays emitted from the beta decay of these radioisotopes in air. The spectrometer was utilized without air sucking pump and filter paper in order to reflect real-time radioisotope concentration in the surrounding air. The spectrometer was calibrated by use of artificial gaseous Ar-41, Kr-85m, and Xe-125, 133, 135 released to a sealed chamber. Detection limit and possible application in field monitoring are discussed.
