| Popis: | The aim of the present work is to determine natural and artificial radioactivities in the twenty tea samples available at the local Vietnamese market using gamma spectrometry with HPGe detector. The radioactivity concentrations of 238U, 232Th, 40K and 137Cs in their mean value were 3.4 ± 0.3 (Bq kg−1), 16.4 ± 0.8 (Bq kg−1), 564 ± 8 (Bq kg−1), and 1.6 ± 0.1 (Bq kg−1), respectively. The result was compared with the those found in the previous research. |
