Abstract  

The dominant development in the radiometrics techniques for the analysis of short and medium-lived radionuclides in the environment was the utilisation of large volume Ge detectors in underground laboratories with additional anti-cosmic shielding. In the mass spectrometry sector, applications of Accelerator Mass Spectrometry (AMS) and Inductively Coupled Plasma Mass Spectrometry (ICPMS) for the analysis of long-lived radionuclides in the environment are the most important recent achievements. These developments in both sectors did not only considerably decrease the detection limits for several radionuclides (up to several orders of magnitude), but they also enable to decrease sample volumes so that sampling, e.g. of the water column, can be much easier and more effective. Applications of radiometrics and mass spectrometry techniques in isotope oceanography, specifically on the distribution of 3H, 14C, 90Sr, 129I, 137Cs, 239Pu and 240Pu in the water column of the North Pacific and South Indian Oceans are presented and discussed.
