After the earthquake and the tsunami occurred in Japan on March 2011, four of the Fukushima reactors had released in air a large amount of radioactive isotopes that diffused all over the world. The presence of airborne (131)I, (134)Cs, and (137)Cs in air particulate due to this accident were detected and measured in the Low Radioactivity Laboratory operating in the Department of Environmental Sciences of the University of Milano-Bicocca. The sensitivity of the detecting apparatus is of 0.2 uBq/m(3) of air. Concentration and time distribution of these radiocontaminations ranging from a few to 400 uBq/m(3) for the (131)I and of a few tens of uBq/m(3) for the (137)Cs and (134)Cs.
2011 年 3 月，日本发生地震和海啸后，福岛的四个反应堆向空气中释放了大量放射性同位素，这些同位素扩散到了世界各地。由于这次事故，空气中的（131）I、（134）Cs 和（137）Cs 等气载放射性核素在米兰比可卡大学环境科学系的低放射性实验室中被检测到并测量到。探测仪器的灵敏度为 0.2uBq/m(3)的空气。这些放射性核素的浓度和时间分布范围从（131）I 的几个到 400 uBq/m(3)，（137）Cs 和（134）Cs 的则为几十 uBq/m(3)。
