The activity concentrations of 137Cs, 40K, 232Th, 238U and 226Ra were measured in surface soil samples from East and South of Marmara region, Turkey. The physico-chemical parameters (organic matter, CaCO3 contents and pH-value) of the soil samples were determined in the samples collected from 100 sampling stations. The average activity concentrations of 137Cs, 40K, 232Th, 238U and 226Ra were found to be 27.46+/-21.84, 442.51+/-189.85, 26.63+/-15.90, 21.77+/-12.08 and 22.45+/-13.31 Bq kg(-1), respectively. The mean value of total annual external gamma radiation dose equivalent for the natural radionuclides was calculated to be 54.86 microSv. The current data were compared with those found in the other locations of Turkey and different countries.
在土耳其马尔马拉地区东部和南部的表层土壤样本中，测量了¹³⁷Cs、⁴⁰K、²³²Th、²³⁸U和²²⁶Ra的活度浓度。在从100个采样站采集的土壤样本中，测定了土壤样本的物理化学参数（有机质、碳酸钙含量和pH值）。¹³⁷Cs、⁴⁰K、²³²Th、²³⁸U和²²⁶Ra的平均活度浓度分别为27.46±21.84、442.51±189.85、26.63±15.90、21.77±12.08和22.45±13.31 Bq kg⁻¹。天然放射性核素的年总外照射剂量当量平均值经计算为54.86微希沃特。将当前数据与在土耳其其他地区和不同国家发现的数据进行了比较。
