Özet
The radioactivity levels were determined in 12 different brands of cow milks
consumed in Eastern Black Sea region of Turkey using a high-purity germanium
detector. The mean activity concentrations of 226Ra, 232Th, 40K and 137Cs were 3.2, 1.1,
31.3 and 0.5 Bq.L−1
, respectively. The values were comparable with the concentrations
reported in the other countries. Due to consumption of cow milk, the radiological
impact of them on the inhabitants was calculated by taking the annual intake into
account through ingestion of aforementioned radionuclides. The estimated effective
doses from milk were found to be 21.2 μSv year−1 for 226Ra, 6.1 μSv year−1 for 232Th,
0.1 μSv year−1 for 137Cs and 4.7 μSv year−1 for 40K. The calculated annual effective dose
obtained from all measured radionuclides was much below the UNSCEAR
recommended reference level of 200-800 µSv.y-1 for all milk samples. The obtained
result data will contribute to establish a baseline level of radioactivity in cow milk and
help to develop future guidelines in the country for radiological protection of the
population
