A survey was carried out on the activity concentrations of (210)Pb and (210)Po in cereal grains produced in Finland. The cereal species were wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and barley (Hordeum vulgare), which account for 90% of the Finnish consumption of cereal products. The survey consisted of 18 flour and 13 unprocessed cereal samples and one hulled grain sample from 22 flour mills. According to the results, the mean (210)Pb/(210)Po concentrations in wheat grains, wheat flour, rye flour, oat grains and barley grains were 0.29, 0.12, 0.29, 0.36 and 0.36 Bq kg(-1), respectively. Combined with the consumption rates of the products, we assess that the mean effective doses from (210)Pb and (210)Po in cereal products for the adult male and female population are 22 and 17 μSv per year, respectively.
对芬兰生产的谷物中（210）Pb 和（210）Po 的活度浓度进行了调查。谷物品种包括小麦（Triticum aestivum）、黑麦（Secale cereale）、燕麦（Avena sativa）和大麦（Hordeum vulgare），它们占芬兰谷物产品消费的 90%。该调查包括来自 22 家面粉厂的 18 个面粉和 13 个未加工谷物样本以及一个带壳谷物样本。根据调查结果，小麦粒、小麦粉、黑麦粉、燕麦粒和大麦粒中的（210）Pb/（210）Po 平均浓度分别为 0.29、0.12、0.29、0.36 和 0.36 Bq kg(-1)。结合产品的消费率，我们评估出成年男性和女性从谷物产品中的（210）Pb 和（210）Po 中获得的平均有效剂量分别为 22 和 17 μSv 每年。
