1986年4月26日，位於當時蘇聯境內、現屬Ukraine的切爾諾貝爾核電廠發生重大事故，即著名的Chernobyl disaster。事故源於第四號反應爐在安全測試期間出現設計缺陷與操作失誤，引發劇烈爆炸並釋放大量放射性物質進入大氣層。爆炸後產生的放射性雲團迅速擴散至歐洲多地，對環境與人類健康造成長期影響。事故發生初期，當局未能即時公開資訊，加劇了危機的嚴重性。數以千計的救援人員被派往現場進行滅火與清理工作，其中許多人承受了高劑量輻射。附近城市普里皮亞季被緊急疏散並永久封鎖，成為無人居住的禁區。切爾諾貝爾事件被視為核能歷史上的重大轉折點，促使全球重新檢視核能安全與監管制度，也引發對能源政策與環境風險的長期討論。
English Version
On April 26, 1986, the Chernobyl disaster occurred at a nuclear power plant in what is now Ukraine, marking one of the most catastrophic nuclear accidents in history. The disaster was caused by a combination of reactor design flaws and operator errors during a safety test, leading to a massive explosion in Reactor No. 4. This explosion released a large amount of radioactive material into the atmosphere, forming a radioactive cloud that spread across large parts of Europe. The environmental and health consequences were severe and long-lasting. In the immediate aftermath, authorities delayed public disclosure, worsening the impact of the crisis. Thousands of emergency workers were deployed to contain the damage, many of whom were exposed to dangerous levels of radiation. The nearby city of Pripyat was evacuated and remains largely abandoned, becoming a symbol of the disaster’s lasting effects. The Chernobyl accident fundamentally changed global perceptions of nuclear energy, leading to stricter safety regulations and ongoing debates about the risks and benefits of nuclear power.
