Sažetak
137-Cs concentration was measured in flowers, pollen and honey, samples of which were collected from the Republic of Croatia 4 years after the Chernobyl accident. Radioactivity of 137-Cs was measured by gamma-spectrometry. Cesium in honey corresponds well with 137-Cs contamination of territory in the Republic of Croatia. Activity of 137-Cs in pollen which is higher than in honey indicates that cesium behaves analogously to potassium. The results show that equal cesium concentrations in the surface soil layer results in higher cesium activities in honey in the case of meadow flowers, ie honey bee pasture, zhan in case when pasture is based on bush and tree flowers. Cesium activity average in honey, collected from the Republic of Croatia territory, is < 1% of the permissible level of 600 Bq/kg.
