Sigara tütününün doğal ve yapay radyoaktivitesinin belirlenmesi

Sigara tütünündeki doğal ve yapay radyoaktivite konsantrasyonları %20 rölatif verimli n-tipi HPGe gama spektrometre kullanılarak belirlenmiştir.226Ra, 232Th, 40K, 210Pb ve 137Csradyoaktivite konsantrasyonları ölçülmüştür.Cs radyoaktivite konsantrasyonları ÖMD ( ölçülebilir en düşük aktivite ) değerinin altında bulunmuştur. 226Ra, 232Th, 40K ve 210Pb ortalama radyoaktivite konsantrasyonları sırasıyla 11,9 ± 1,4, 11,7 ± 1,4, 1197,48 ± 143,7 ve 24,9 ± 3,0 Bq/kg olarak bulunmuştur. 226Ra, 232Th, 40K ve 210Pb radyoaktivite konsantrasyonları değerleri dünyadaki diğer çalışmalarda elde edilen sonuçlarla uyuşmaktadır.

Determination of the natural and artificial radioactivity of the tobacco

Natural and artificial radioactivity concentrations of the Tobacco samples were determined using 20% n-type HPGe gamma-ray spectrometer. 226Ra, radioactivity concentrations were found to be MDA ( minimum detectable activity). 226Ra, 232Th, 40K and 210Pb averageradioactivity concentrations were found to be 11,9 ± 1,4, 11,7 ± 1,4, 1197,48 ± 143,7 ve 24,9 ± 3,0 Bq/kg respectively.
