CEZIJ U MESU MEDVJEDA KAO IZVOR DOZNOG OPTEREĆENJA LJUDI U HRVATSKOJ

The study was conducted by the Radiation Protection Unit of the Institute for Medical Research and Occupational Health in Zagreb in collaboration with the Faculty of Veterinary Medicine of University of Zagreb, as part of an extensive monitoring programme of the Croatian environment. Samples collected in 2015 from brown bears that were accidentally killed or culled were analysed by gamma-spectrometry to determine 137 Cs and 134 Cs activity concentrations. In 2015, 134 Cs activity concentrations were found to be very small, near the values of the detection limits and could be attributed to the Fukushima-Daiichi nuclear accident of March 2011. The average 137 Cs activity concentration in brown bear meat was found to be 3.4 ± 1.5 Bqkg -1 and that of 134 Cs 0.05 ± 0.02 Bqkg -1 . The estimation of the effective dose incurred by game meat ingestion was made for an adult member of the general population in Croatia, assuming that all of the ingested meat (0.3 kg per year according to the Croatian Bureau of Statistics) originated from bears. The annual effective dose due to 137 Cs intake was assessed to be 13 nSv and due to intake of 134 Cs only 0.3 nSv. For the dose assessment of critical populations, i.e. hunters, data from studies by the Croatian Food Agency (CFA) were used. An adult person consumes on average 36.55 g (0.32 - 320 g) of game meat daily. Using CFA data, the average annual meat consumption contributed to an effective dose of 0.58 µSv (5 nSv - 5.1 µSv) from 137 Cs and 12 nSv (0.1 - 107 nSv) from 134 Cs. For comparison, the intake of 137 Cs from consumption of poultry contributed to an annual effective dose of 104 nSv, pork 21 nSv and beef or veal 28 nSv. This study was an attempt to demonstrate the importance and need for the individualization of dose assessment calculations and food control based on the nutritional habits of the average consumer and activity concentration of a certain radionuclide on the local level.
