歐洲多地檢測到不明核輻射
A mysterious increase in radiation levels over northern Europe was detected this month by authorities from several countries, although no nation has yet come forward to claim responsibility for the anomaly.
本月，來自幾個國家的專家探測到歐洲北部的輻射水平神祕升高，目前還沒有國家站出來爲這一反常現象負責。
The subtle radiation spike – at levels that are considered harmless to humans, but significant enough to be picked up by radiation monitoring stations – began to make headlines last week, with European authorities announcing new readings of human-made radionuclide particles in the atmosphere.
輻射值的微妙升高目前被認爲對人體無害，但也足以被輻射監測站探測出來。這一情況從上週開始就登上了新聞頭條，歐洲當局公佈了大氣中人造放射性核素粒子的新讀數。
"Very low levels of the radioactive substances cesium-134, cesium-137, cobalt-60 and ruthenium-103 were measured," the Swedish Radiation Safety Authority tweeted on Tuesday.
瑞典輻射安全局週二在推特上寫道：“檢測到放射性物質銫-134、銫-137、鈷-60和釕-103的含量很低。”
"The levels measured are so low that they pose no danger to people or the environment."
“含量太低，對人類或環境都不構成威脅。”
Similar observations were also made by radiation protection authorities in Norway and Finland.
挪威和芬蘭的輻射防護部門也進行了類似的觀測。
Later last week, Lassina Zerbo, the Executive Secretary of the Comprehensive Nuclear-Test-Ban Treaty Organisation, tweeted a map outlining the possible source region of the anomaly, most of which was territory inside Russia, but also parts of Finland, Sweden, Denmark, and Norway.
上週晚些時候，《全面禁止核試驗條約》的行政祕書Lassina Zerbo在推特上發佈了一張地圖，勾勒出異常現象可能的源區，其中大部分位於俄羅斯領土範圍內，但也包括芬蘭、瑞典、丹麥和挪威的部分地區。
"These isotopes are most likely from a civil source," Zerbo tweeted, suggesting a source related to nuclear power production, not nuclear weapons.
Zerbo在推特上寫道：“這些同位素最有可能是民用的，”來源與核電生產有關，但不是核武器。
"We are able to indicate the likely region of the source, but it's outside the CTBTO's [Comprehensive Nuclear-Test-Ban Treaty Organization] mandate to identify the exact origin."
“我們能指出來源的可能區域，但要準確定位來源就超出了《全面禁止核試驗條約》的授權範圍。”
Last Friday, the Dutch National Institute for Public Health and the Environment (RIVM) announced that, based on an analysis of the available data, the "combination of radionuclides may be explained by an anomaly in the fuel elements of a nuclear power plant".
上週五，荷蘭國家公共衛生與環境研究所宣佈，基於對所獲得數據的分析，“可以說這些放射性核素組合與核電站的燃料元件異常有關”
On the available evidence, the organisation suggested that the radioactive particles detected had come from the direction of western Russia, but clarified that this did not mean they were definitively linked with Russian power plants.
根據已有證據，該組織表示，探測到的放射性粒子來自於俄羅斯西部的方向，但又說這並不意味着一定與俄羅斯的電廠有關係。
