title: Radioactivity of honeys from Poland after the Fukushima accident.
abstract: Concentration of radioactive isotopes in honey constitutes an important bioindicator of environmental radiation. One hundred six honey samples were collected from hives and from bottled honey provided by beekeepers from north-eastern Poland in 2010, before the Fukushima accident, and during the two-year period directly following this catastrophe (2011-2012). Cesium-137 (Cs-137) and potassium-40 (K-40) were determined in lime, multifloral, buckwheat, honeydew and other kinds of honey samples. The obtained mean concentrations of Cs-137 and K-40 (Bq kg(-1)) in honey samples were: 1.19 and 32.92 in 2010, 0.90 and 31.13 in 2011, 1.31 and 36.06 in 2012, respectively. Significant differences were not observed. Therefore, the studied honey samples collected after the Fukushima accident are found to be safe for humans with levels of Cs-137 and K-40 not posing any threats. However, the total concentration of Cs-137 and K-40 in samples stopped decreasing in 2010-2011 and showed a slight increase in 2012. This relation may suggest the impact of pollution from Fukushima and requires further research in the coming years.
