Abstract

The activity concentrations of the natural radionuclides (238U, 232Th, 40K) in the agricultural soils around the Jordanian petroleum refinery in Zarqa city, Jordan, were investigated. The soil samples were collected from three different agricultural regions (X, Y and Z). The 232Th activity concentration was found to be too low in all samples. The average activity concentrations in Bq/kg were found to be: 40.1±1.6 for 238U and 372.6±11.9 for 40K in X-site, 38.3±1.9 for 238U and 486.4±15.0 for 40K in Y-site, and 45.4±1.3 for 238U and 313.3±11.1 for 40K in Z-site. Our findings are within the worldwide average values (UNSCEAR, 2000). The absorbed dose rates were calculated and found to be in the range of 20.86-47.62 nGy/h with an overall average value of 34.66 nGy/h. The average outdoor annual effective dose equivalent was estimated to be 41.13 ± 11.64 μSvy−1 which is below the world average of 70 μSvy−1.

约旦扎尔卡约旦炼油厂周围农业土壤样品的放射性浓度和剂量评估

对约旦扎尔卡市约旦炼油厂周围农业土壤中天然放射性核素(238U、232Th、40K)的活度浓度进行了调查。从X、Y、Z三个不同的农业区采集土壤样品，发现所有样品的232Th活性浓度都过低。x位点238U和40K的平均活性浓度分别为40.1±1.6和372.6±11.9,y位点238U和40K的平均活性浓度分别为38.3±1.9和486.4±15.0,z位点238U和40K的平均活性浓度分别为45.4±1.3和313.3±11.1。我们的研究结果在世界平均值之内(UNSCEAR, 2000)。计算吸收剂量率范围为20.86 ~ 47.62 nGy/h，总体平均值为34.66 nGy/h。室外年平均有效剂量当量为41.13±11.64 μSvy−1，低于70 μSvy−1的世界平均水平。
