In this paper, activity concentrations of radiocesium in mushrooms from various locations in the Czech Republic and the Slovak Republic in the years 2000-2004 are presented. Summary reports of Czech regulatory bodies have judged the average activity concentrations in mushrooms to be remarkably below the maximum permissible level of contamination. However, there are certain regions where radiocesium activities have approached the maximum permissible level for contamination of basic foodstuff. For example, the highest activity concentration of (137)Cs measured by gamma-spectrometry was 2,263 Bq kg(-1) (on a dry mass basis), in Xerocomus badius from Staré Ransko (a locality in the Czech-Moravian Highlands, Czech Republic). The highest activity concentration of (137)Cs measured in Slovakia was 966 Bq kg(-1) (on a dry mass basis), for Suillus luteus from Senica. For comparison, the corresponding activity concentration in a sample taken within the 30 km zone around Chernobyl was measured to be 6,000 Bq kg(-1) (on a dry mass basis). Our results have also demonstrated remarkably lower activity concentrations of (137)Cs in Slovakia compared to those in the Czech Republic.
本文介绍了2000 - 2004年捷克共和国和斯洛伐克共和国不同地点蘑菇中放射性铯的活度浓度。捷克监管机构的总结报告判定，蘑菇中的平均活度浓度显著低于最大允许污染水平。然而，某些地区的放射性铯活度已接近基本食品污染的最大允许水平。例如，通过伽马能谱法测得的（137）铯最高活度浓度为2263 Bq kg⁻¹（以干质量计），来自Staré Ransko（捷克共和国捷克 - 摩拉维亚高地的一个地方）的褐疣柄牛肝菌。在斯洛伐克测得的（137）铯最高活度浓度为966 Bq kg⁻¹（以干质量计），来自Senica的黄斑牛肝菌。作为比较，在切尔诺贝利周围30公里区域内采集的一个样本中，相应的活度浓度经测量为6000 Bq kg⁻¹（以干质量计）。我们的结果还表明，与捷克共和国相比，斯洛伐克的（137）铯活度浓度显著更低。
