Türk Çayı Örneklerinde Radyoaktivitenin Belirlenmesi

Türk çayı örneklerinin doğal ve yapay radyoaktivite konsantrasyonları %20 n-tipi HPGe dedektör kullanılarak belirlenmiştir. 238U, 226Ra, 232Th, 228Ra, Th, 40K, 210Pb, 7Be ve 137Csradyoaktivite konsantrasyonları ölçülmüştür. 238U, 226Ra, 232Th, Ra, 228Th radyoaktivite konsantrasyonları MDA bulunmuştur. 7Be, 210Pb, 40K ve 137Cs radyoaktivite konsantrasyonlarının ortalama değerleri sırasıyla 30.8 ± 2.3, 49.4 ± 4.4, 485.4±38.6 ve 38.8±2.4 Bq kg-1 bulunmuştur

Determination of the radioactivity in the Turkish tea samples.

Natural and artificial radioactivity concentrations of the Turkish tea samples were determined using 20% n-type HPGe gamma-ray spectrometer. 238U, 226Ra, 232Th, 228Ra, 228Th, 40K, 210Pb, 7Be and 137Csradioactivity concentrations were measured. 238U, 226Ra, 232Th, 228Ra, 228Th radioactivity concentrations were MDA. 7Be, 210Pb, 40K and 137Cs radioactivity concentrations mean values were found 30.8 ± 2.3, 49.4 ± 4.4, 485.4±38.6 and 38.8±2.4 Bq kg-1, respectively.
