Alpha and gamma spectrometry for determination of natural and artificial radionuclides in tea, herbal tea and camomile marketed in Italy

Several kinds of tea, camomile and herbal tea were analysed to determine natural and artificial radioactivity. The radionuclides were determined by alpha (210Po) and gamma (228Ac, 214Pb, 214Bi, 210Pb, 40K and 137Cs) spectrometry. 228Ac ranged between 0.6 and 9.0Bq kg−1dry; 210Po between 1.90 and 36....
