Transfer factors are the most important parameters required for mathematical modeling used for environmental impact assessment of radioactive contamination in the environment. In this paper soil to leaf transfer factor for the radionuclides ⁴⁰K, ²²⁶Ra, ¹³⁷Cs and ⁹⁰Sr is estimated for Kaiga region in Karnataka state, India. Among the plants in which study is carried out, ²²⁶Ra, ⁴⁰K, ¹³⁷Cs and ⁹⁰Sr activity in leaves of herbaceous plants is higher than that of tree leaves. Soil to leaf transfer factor for ²²⁶Ra, ⁴⁰K, ¹³⁷Cs and ⁹⁰Sr was found to be in the range of 0.03-0.65, 0.32-8.04, 0.05-3.03 and 0.42-2.67 respectively.
转移因子是环境影响评价中用于放射性污染环境数学建模所需的最重要参数。本文估算了印度卡纳塔克邦卡加地区的放射性核素 ⁴⁰K、²²⁶Ra、¹³⁷Cs 和 ⁹⁰Sr 的土壤到叶片转移因子。在所研究的植物中，草本植物叶片中的 ²²⁶Ra、⁴⁰K、¹³⁷Cs 和 ⁹⁰Sr 活性高于树木叶片。²²⁶Ra、⁴⁰K、¹³⁷Cs 和 ⁹⁰Sr 的土壤到叶片转移因子范围分别为 0.03-0.65、0.32-8.04、0.05-3.03 和 0.42-2.67。
