In the present study, the transfer factors of the natural radionuclides 238U, 232Th, and 40K were estimated for several crops cultivated in farms in the suburbs of Baghdad and one farm in Al-Najaf. The transfer factor (TF) is the ratio of activity transfers from soil to plant. The specific activities of the natural radionuclides were measured with a gamma-ray spectrometer with a HPGe detector. The crops include cereals (rice and wheat), fruits (lemons and oranges), podded vegetables (vigna and okra), fruity vegetables (chili peppers and Solanum melongena), and leafy vegetables (Apium graveolens, Raphanus sativus, and Ocimum basilicum). The results showed that the highest transfer factors for 238U, 232Th, and 40K are 0.32, 0.70, and 3.44, respectively, in wheat. The average transfer factors for 238U and 232Th were founded 0.23 and 0.2 which are lower than the default unitiy value but the 1.85 were reported for 40K higher than unity.

天然放射性核素的植物转移因子和某些农作物的土壤辐射危害

在本研究中,估计了在巴格达郊区的农场和Al-Najaf的一个农场种植的几种作物的天然放射性核素238 U,232 Th和40 K的转移因子。转移因子(TF)是从土壤到植物的活性转移比。天然放射性核素的比活度用带有HPGe检测器的伽马射线光谱仪测量。农作物包括谷类(大米,小麦),水果(柠檬和橙子),荚蔬菜(豇豆和秋葵),水果蔬菜(辣椒和茄子),和绿叶蔬菜(芹菜芹萝卜,和罗勒)。结果表明,小麦中238 U,232 Th和40 K的最高传递因子分别为0.32、0.70和3.44。对于一般的传输因子238 U和232钍都成立0.23和0.2,它们比默认unitiy值低,但被报告为1.85 40 ķ大于一个单位。
