Radioactivity evaluation and radiation dosimetry assessment in Greek honey

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.
