Abstract
Method of determining the activity concentration of the radio nuclides in waste gases of nuclear power plants by bleeding a part of the gas stream, compressing it to a high superatmospheric pressure, passing the compressed gas into a high pressure chamber where the specific nuclides are measured by means of a calibrated Ge (Li) detector, and returning the gas from the chamber at reduced pressure to the gas stream. The activity concentration of the gas in the high-pressure vessel permits measurement of the specific nuclides, and also permits detection of waste gas activities which are below the customary detection limits.
