A study on the activity concentrations of natural radionuclides and annual effective dose values in some tobacco samples

Tobacco samples were collected from different tobacco markets Antalya in Turkey. To calculate natural radionuclides activity concentration, counted for 86400 seconds by using high purity germanium (HPGe) detector. Activity concentrations of 226Ra, 232Th and 40K found higher than minimum detectable (MDA). 137Cs was not detected any sample. concentration range 83±15 Bqkg-1 to 325±45 Bqkg-1, 29±5 207±37 (2.09±0.28)x103 (5.07±0.90) x103 respectively. In addition, annual effective dose value calculated. The values owing inhalation adults change 2.76 9.91 µSvy-1 214Pb, 5.69 27.69 214Bi, 5.72 40.41 228Ac, 42.23 102.37 40K. total 0.05 0.16 mSvy-1.
