Mission of the Laboratory is development of measurement techniques for radiocarbon and tritium activita at the international level and application of natural radioactive (¹⁴C, ³H) and stable (²H, ¹³C, ¹⁸O) isotopes in multidisciplinar scientific research as in archaeology, geology, hydrogeology, palaeoclimatology and ecology, as well as the study of interaction of low-energy radiation and gases. These investigations are in accordance with strategic research directives in Croatia, such as basic physico-chemical investigations in environment and investigations that contribute to the Croatian identity.
