Abstract A technical approach to design and carry out an experiment to determine the uptake of selected radionuclides in site-specific conditions in Kuwait was developed and successfully executed for developing a radioecological decision support system. The radionuclides from soil-to-plant transfer factors have been obtained for leafy and non-leafy vegetables, and root crops cultivated in Kuwait. Two types of vegetated soils were selected and spiked with high concentrations of three relatively short-lived selected radionuclides (85Sr, 134Cs, and 133Ba). The highest strontium and barium transfer factors were found in the order: leafy vegetables > root crops > non-leafy vegetables. The approximate range of radiocesium transfer factor was found to be low in all plant groups and was comparable to those reported elsewhere in different soil types of temperate and tropical environments. A strong negative correlation between the obtained transfer factors and the distribution coefficient of the radionuclide in soil was found. It is recommended to adopt the newly derived parameters for the sensitive areas in Kuwait and other Gulf countries instead of using the generic parameters, whenever dose calculation codes are used. This will help to more accurately assess and predict the end results of the committed effective dose equivalent through ingestion pathway.

估算放射性锶、放射性铯和放射性钡从干旱土壤到植物的转移：科威特案例研究

摘要 为开发放射性生态决策支持系统，开发并成功实施了一种技术方法，用于设计和实施确定选定放射性核素在科威特特定地点条件下的吸收情况的实验。已经从科威特种植的叶菜和非叶菜以及块根作物中获得了来自土壤到植物转移因子的放射性核素。选择了两种类型的植被土壤，并在其中添加了高浓度的三种寿命相对较短的选定放射性核素（85Sr、134Cs 和 133Ba）。锶和钡转移因子最高的顺序是：叶类蔬菜>块根作物>非叶类蔬菜。发现放射性铯转移因子的大致范围在所有植物组中都很低，并且与其他地方报告的温带和热带环境不同土壤类型中的范围相当。发现所获得的转移因子与土壤中放射性核素的分布系数之间存在强烈的负相关关系。每当使用剂量计算代码时，建议对科威特和其他海湾国家的敏感区域采用新导出的参数，而不是使用通用参数。这将有助于更准确地评估和预测通过摄入途径的待积有效剂量当量的最终结果。每当使用剂量计算代码时，建议对科威特和其他海湾国家的敏感区域采用新导出的参数，而不是使用通用参数。这将有助于更准确地评估和预测通过摄入途径的待积有效剂量当量的最终结果。每当使用剂量计算代码时，建议对科威特和其他海湾国家的敏感区域采用新导出的参数，而不是使用通用参数。这将有助于更准确地评估和预测通过摄入途径的待积有效剂量当量的最终结果。
