Radioactivity evaluation and radiation dosimetry assessment in Greek honey

Abstract

Greek honey was examined for 238U, 234U, 210Pb, 210Po, 40K, and 137Cs levels. 238U was calculated from 0.013 ± 0.007 Bq kg−1 to 0.10 ± 0.02 Bq kg−1 while 234U ranged from 0.017 ± 0.009 Bq kg−1 to 0.11 ± 0.03 Bq kg−1. 210Pb measured from 0.04 ± 0.02 Bq kg−1 to 1.70 ± 0.26 Bq kg−1 whereas 210Po activity determined between 0.02 ± 0.01 Bq kg−1 and 2.31 ± 0.34 Bq kg−1. 40 K found at the range of 7.9 ± 1.6 Bq kg−1 to 102.2 ± 19.7 Bq kg−1 and 137Cs 0.3 ± 0.1 Bq kg−1 up to 0.8 ± 0.1 Bq kg−1. Uranium isotopes and 210Po were determined via alpha spectrometry. 210Pb was also indirectly determined by alpha spectrometry. 40 K and 137Cs were measured through γ-ray spectrometry. An annual dose calculation was performed for different age groups.
