In radioecological studies, soil to plant transfer factors (TF) is commonly used to estimate the food chain transfer of radionuclides, which is an important parameter to assess ingestion doses to humans. Rice is an important (Oryza sativa L.) staple crop in tropical countries and is the major food crop consumed all over the world. Out of the seven countries (India, Pakistan, Bangladesh, Nepal, Bhutan, and the island nations like Sri Lanka and Maldives) of the Indian subcontinent, Bangladesh, Sri Lanka, and Maldives along with a major region of India fall under tropical climate class according to Köppen climate classification. Because, the soil to rice TF under equilibrium conditions are not available for all radionuclides, TF of naturally existing stable elements, which are analogues of radionuclides were compiled. This review paper presents the collection of the TF data of soil to grain and stems & shoots of rice plant for eighteen elements. Data were generated mainly from different sub climatic regions of the tropical environment of India and Bangladesh. An overview of the compilation, analysis, and discussion of the extent and limitations of the data is presented.
在放射性生态学研究中，土壤到植物转移因子（TF）通常用于估计放射性核素在食物链中的转移，这是评估人类摄入剂量的一个重要参数。水稻是热带国家的重要（Oryza sativa L.）主食作物，也是全世界主要的食用作物。在印度次大陆的七个国家（印度、巴基斯坦、孟加拉国、尼泊尔、不丹以及斯里兰卡和马尔代夫等岛国）中，孟加拉国、斯里兰卡和马尔代夫以及印度的一个主要地区根据柯本气候分类属于热带气候区。由于在平衡条件下并非所有放射性核素的土壤到水稻 TF 都可用，因此编译了天然存在的稳定元素的 TF，这些元素是放射性核素的类似物。本文综述了对 18 种元素的土壤到稻谷和茎秆与稻穗 TF 的 TF 数据的收集。这些数据主要是从印度和孟加拉国热带环境的不同次气候区生成的。本文对数据的汇编、分析和讨论进行了概述，包括数据的范围和局限性。
