Measurement of C-14 in air, generated from a low power (300 kW) training reactor, has been carried out A simple method has been applied using barium hydroxide for the absorption of CO2, followed by conversion of barium carbonate to benzene for analysis using liquid scintillation counting. Air from the reactor stack and from various sites in the immediate vicinity has been analysed for the determination of C-14. In order to assess the environmental hazards to the population, the collected data has been used to calculate radiation dose due to C-14.
