Long-term investigations of <sup>134</sup>Cs and <sup>137</sup>Cs Activity Concentrations in Honey from Croatia
This paper presents the results of long-term post-Chernobyl investigations of <sup>134</sup>Cs and <sup>137</sup>Cs activity concentrations in multifloral and chestnut honey sampled in north-west Croatia. For both radionuclides, the activity concentrations peaked in May 1986, decreasing exponentially until the mid-1990s, when they fell under the detection limit for both radionuclides. After the Fukushima-Daiichi accident in 2011, the presence of both radionuclides in honey was detected once again. The ecological half-life was estimated to be 1.67 and 1.45 years for <sup>137</sup>Cs and <sup>134</sup>Cs, respectively. The correlation between <sup>134</sup>Cs and <sup>137</sup>Cs activity concentrations in fallout and honey was very good, indicating fallout to be the main source of honey contamination. The observed <sup>134</sup>Cs/<sup>137</sup>Cs activity ratio in honey was similar to the ratio found in other environmental samples. The estimated collective effective doses for the Croatian population incurred by honey consumption indicate that honey was not a critical pathway for the transfer of <sup>134</sup>Cs and <sup>137</sup>Cs from fallout to humans.
