Abstract

In environmental research, the measurements and evaluation of the isotope ratios represent an important step in explanation of many processes. There are nuclear processes in the environment where stable noble gas isotopes as well as alpha- and beta-decay or spontaneous fission are generated. Therefore, the isotope ratio and concentration can change to such a pitch that notable explanation about these processes can be given in the course of the evaluation of isotope ratio values. The most often used measurement is the tritium-helium method to determine the tritium concentration of water by 3He ingrowth. The noble gas isotope ratios can be measured from dissolved gas of groundwater or headspace gases. The measurement is done by a VG5400 noble gas mass spectrometer.
