Sažetak
Three methods for low-level radiocarbon measurement and two methods for measurement of low-level tritium activity in environmental samples have been developed in the Zagreb Radiocarbon and Tritium Laboratory. Various sample preparation methods are used for 14C (CH4 synthesis, benzene synthesis, CO2 absorption) and 3H (CH4 synthesis, water distillation). A gas proportional counter and a liquid scintillation counter are used for measurement. Basic parameters (sample quantity, background count rate, efficiency, figure of merit, limit of detection) of the methods are compared, as well as 14C and 3H activities determined by different techniques.
