137Cs and 90Sr in milk from the Osijek region
Radioactivity measurements and monitoring of the human environment in Croatia are part of the monitoring programme carried out by the Radiation Protection Unit of the Institute for Medical Research and Occupational Health in Zagreb. Among other radionuclides and samples, this includes radiostrontium and radiocaesium in milk. The objective of this paper was to present and discuss the activity concentrations of 137Cs and 90Sr in milk collected in the Osijek region in five consecutive years (from 2011 to 2015). The 137Cs activity concentrations ranged from 0.08 Bqm-3 to 65.88 Bqm-3, except for May 2011 when an activity concentration of 900.62 Bqm-3 was measured. This high value contributed to a higher effective dose for 2011. The 90Sr activity concentration ranged from 14.56 Bqm-3 to 86.08 Bqm-3. The average activity concentration for each year and radionuclide was calculated and the effective doses received from milk consumption were estimated for the adult population of the Osijek region. The effective doses received from 137Cs uptake by milk consumption ranged from 4 nSv up to 168 nSv for 2011. This effective dose was one order of magnitude higher than the effective doses for the four other years. The effective doses received from 90Sr uptake by milk consumption ranged from 51 nSv to 119 nSv. Continuous control and monitoring of radioactivity in food and the environment are necessary to detect possible future changes in radioactivity levels in the environment. This will result in the protection of the population from the negative effects of ionizing radiation.
