At the Mayak Industrial Reprocessing Complex in Russia’s southern Urals, a storage tank holding nitrate acetate salts exploded in 1957, releasing a massive amount of radioactive material over 20,000 square kilometers, forcing the evacuation of 272,000 people. In September 1994, an explosion at Indonesia’s Serpong research reactor was triggered by the ignition of methane gas that had seeped from a storage room and exploded when a worker lit a cigarette.
1957年在俄罗斯南乌拉尔地区的马雅克工业再处理综合体（Mayak Industrial Reprocessing Complex），一个存有硝基乙酸盐的储藏罐发生破裂并泄漏出大量放射性物质，影响范围超过2万平方公里，27.2万人被迫搬迁。在1994年9月，印尼塞尔蓬(Serpong)研究核反应堆附近一间储藏室发生甲烷气体泄漏，随后一名工人点燃香烟引发爆炸并波及到反应堆。
