Assessment of tritium exposure through urine samples analysis from selected Indonesian radiation workers

In this study tritium exposure was assessed through urine samples analysis by the determination of tritium concentration and effective dose of selected 25 laboratory radiation workers in non-nuclear power plant (non-NPP) facility and 15 people of general public in Jakarta. The samples were mixed with activated charcoal, filtered, and distilled before analysis using liquid scintillation counter. It is revealed that the concentration of tritium levels in urine varied substantially depending not only on the job category but also their water intake, metabolism, and environment. These findings are important as reference data for evaluating the radiological impact on the population from future tritium contamination in Indonesia.
