对几种茶、甘菊和草药茶进行了分析，以确定天然和人工放射性。放射性核素用α（Po-210）和γ（Ac-228、（214）Pb、Bi-214、（210）Pb、K-40和（137）Cs）光谱法测定。（228）AC介于0.6和9.0 Bq kg（干）之间（-1）; Po-210介于1.90和36.1 Bq kg（干）之间（-1）;（214）Pb和Bi-214介于0.7和4.9 Bq kg（干）之间（-1）; Pb-210介于
Several kinds of tea, camomile and herbal tea were analysed to determine natural and artificial radioactivity. The radionuclides were determined by alpha (Po-210) and gamma (Ac-228, (214)pb, Bi-214, (210)pb, K-40 and (137)cs) spectrometry. (228)AC ranged between 0.6 and 9.0 Bq kg(dry)(-1); Po-210 between 1.90 and 36.1 Bq kg(dry)(-1); (214)pb and Bi-214 between 0.7 and 4.9 Bq kg(dry)(-1); Pb-210 between
