Application Practice of ICP-MS in Nuclear Geology

Although inductively coupled plasma mass spectrometry （ICP-MS） technology has been developed for nearly 40 years, it is still the most influential high sensitivity and high efficiency analysis technology in the field of inorganic element analysis. In the field of nuclear geology, ICP-MS has become the core technology of uranium geological exploration and geological disposal of high-level radioactive waste, providing a large number of analytical test data for nuclear geological research and production every year. The samples for ICP-MS analysis include water, soil, sediment, rock, mineral, gas and natural analogues. More than 70 elements in those samples have been measured in the past years. This paper summarized the application of ICP-MS in nuclear geology in our laboratory.
