Radionuclide concentration in cabbage samples due to gamma radiation in samsun, Turkey

Abstract

Establishing of radioactivity planes in foodstuff has emphasis because it allows the evaluation of population exposure to radiation by take nourishment. In this paper, the activity concentrations of Ra-226, Th-232, K-40 and Cs-137 were determined in cabbage samples collected from Samsun city of Turkey using a gamma ray spectrometry method with a HPGe detector. The mean concentration value of Ra-226, Th-232, K-40 and Cs-137 in cabbage samples were 1.11 +/- 0.03 Bqkg(-1,) 1.44 +/- 0.04 Bqkg(-1), 743.75 +/- 21.21 Bqkg(-1) and 0.18 +/- 0.003 Bqkg(-1), respectively. The calculated total annual effective dose received from Ra-226, Th-232, K-40 and Cs-137 due to cabbage samples by population of Samsun province was quite lower than the World average value as suggested by UNSCEAR.
