国际原子能机构派往哈萨克斯坦的代表团研究了塞米巴拉金斯克试验场目前的环境污染和核试验的暴露风险。在这次任务中，EML 科学家收集了原位伽马射线光谱，测量了外部伽马剂量率，并收集了土壤样本。除犁铧区域和接近零地的区域外，所访问的所有区域的外部剂量率均在典型环境水平内。零地半径 15 公里内的测量显示 137 Cs、 152 Eu 和 60 Co 水平升高。距零地约 1 km 内的剂量率范围为 500 至 30000 nGy·h−1。
The International Atomic Energy Agency's Mission to Kazakhstan studied the present environmental contamination and the exposure risk from nuclear tests performed at the Semipalatinsk Test Site. On this mission, EML scientists collected in-situ gamma-ray spectra, measured external gamma dose rates, and collected soil samples. With the exception of plowshare areas and near ground zero, all the areas visited had external dose rates within typical environmental levels. Measurements within a 15 km radius of ground zero showed elevated levels of137Cs,152Eu, and60Co. The dose rate within ≈1 km of ground zero ranged from 500 to 30000 nGy·h−1.
