title: Determination of gaseous radionuclide forms in the stack air of nuclear power plants.
abstract: The determination of gaseous forms of radionuclides in ventilation stacks utilising grab samples was performed as a part of independent monitoring of nuclear power plants in the Czech Republic. The activities of radionuclides (e.g. (41)Ar, (133)Xe, (135)Xe, (85m)Kr, (87)Kr, and (131m)Xe) were determined by semiconductor gamma-ray spectrometry in samples collected into pressure vessels. Radiochemical preparation of samples for determination of (14)CO(2), combustible (14)C forms, and (85)Kr was performed after the radioactive decay of radionuclides with short half-life.
