Transfer factors of (40)K, (238)U, (210)Pb, and (210)Po from soil to some agriculture crops in various locations in south of Syria (Dara'a and Assuwaydaa districts) have been determined. Soil and vegetable crops (green pepper, cucumber, tomato, and eggplant), legumes crops (lentil, chickpea, and broad bean), fruit trees (apple, grape, and olives) and cereals (barley and wheat) were collected and analyzed for (238)U, (210)Pb, and (210)Po. The results have shown that higher transfer factors (calculated as Bqkg(-1) dry wt. plant material per Bqkg(-1) dry wt. soil) for (210)Po, (210)Pb and (238)U were observed in vegetable leaves than fruits and cereals leaves; the highest values of transfer factor (TF) for (238)U were found to be 0.1 for straw of chickpea. Transfer factors for (210)Po varied between 2.8x10(-2) and 2 in fruits of eggplant and grain of barley, respectively. In addition, several parameters affecting transfer factors of the radionuclides were evaluated. The results can be considered as base values for TF of natural radionuclides in the region.
已测定叙利亚南部不同地点（达拉阿和苏韦达区）土壤中⁴⁰K、²³⁸U、²¹⁰Pb和²¹⁰Po向一些农作物的转移因子。采集了土壤和蔬菜作物（青椒、黄瓜、番茄和茄子）、豆类作物（小扁豆、鹰嘴豆和蚕豆）、果树（苹果、葡萄和橄榄）以及谷物（大麦和小麦），并对其进行²³⁸U、²¹⁰Pb和²¹⁰Po分析。结果表明，在蔬菜叶片中观察到²¹⁰Po、²¹⁰Pb和²³⁸U的转移因子（以每Bqkg⁻¹干重土壤中Bqkg⁻¹干重植物材料计算）高于果实和谷物叶片；鹰嘴豆秸秆中²³⁸U的转移因子（TF）最高值为0.1。茄子果实和大麦籽粒中²¹⁰Po的转移因子分别在2.8×10⁻²和2之间变化。此外，还评估了影响放射性核素转移因子的几个参数。这些结果可被视为该地区天然放射性核素转移因子的基础值。
