This paper specifically discusses a radiological risk assessment due to RDDs (Radiological Dispersion Devices) containing Cs-137 in the metropolitan area of Seoul, South Korea. The comparison of an effective dose caused by airborne plume and deposited Cs-137 is performed with and without consideration of the wind direction. When the dose is computed conservatively, an effective dose is around twice that of a dose computed realistically. Monte Carlo simulations showed that the 95% confidence interval for morbidity was 2.40×10(-5) to 8.55×10(-5), and mortality was 3.53×10(-5) to 1.25×10(-4).
本文专门讨论了韩国首尔大都市区因含铯 - 137的放射性散布装置（RDDs）而进行的放射风险评估。在考虑和不考虑风向的情况下，对空气羽流和沉积的铯 - 137所造成的有效剂量进行了比较。当保守计算剂量时，有效剂量约为实际计算剂量的两倍。蒙特卡罗模拟表明，发病率的95%置信区间为2.40×10⁻⁵至8.55×10⁻⁵，死亡率为3.53×10⁻⁵至1.25×10⁻⁴。
