Sažetak
Radioecological investigations regarding fission products in foodstuffs in Croatia are implemented as part of an extended and still ongoing radioactive contamination monitoring programme of the human environment. The programme has been designed and endorsed by the Croatian State Office for Radiological and Nuclear Security and fully harmonized with European legislation, i.e. the European Commission’s recommendation of June 2000 on the application of Article 36 of the Euratom Treaty. For describing the overall possible impact the contaminants have on the entire region, the most efficient sampler would be one that covers the largest area possible. In this sense, honey has been shown to be an excellent biological indicator for detecting radionuclides but also other pollutants such as heavy metals. In Croatia, radiocaesium nuclides like 137 Cs and 134 Cs in honey were first investigated after the Chernobyl accident in 1986. For both radionuclides, the activity concentrations in honey, which peaked in May 1986, decreased exponentially and the estimated ecological residence time, corrected for radioactive decay, was found to be 1.23 y for 137 Cs and 1.07 y for 134 Cs. In the early 1990s, activity concentrations in honey for both radionuclides were under the detection limit, but again rose after the Fukushima Daiichi accident. Effective radiation doses due to radiocaesium, received by the Croatian population by honey consumption, even in the year of the Chernobyl accident were estimated to be very small, the per caput dose being < 1 μSv. Based on radioecological investigations of honey, we argue that the mobility of honey bees and their ability to integrate all exposure pathways could add another level of confidence to the present monitoring program if honey and other bee-farming products are included in the routine radioecological monitoring programme for the Croatian environment.
