About 160 PBq of (131)I was released into the atmosphere during the accident at the Fukushima Dai-ichi Nuclear Power Plant. The chemistry of radioiodine is complicated, and it can be released in several different forms. In addition, the different physical forms, like molecular iodine, aerosol-form iodine, or organic iodine, would have all behaved differently once in the atmosphere, and would have been removed at different rates. These releases were detected by monitoring stations throughout Japan, and from these measurements, key insights can be made about the different chemical forms that were released, as well as the persistence of each in the environment.
福岛第一核电站事故期间，约160太贝克勒尔的碘-131释放到了大气中。放射性碘的化学性质复杂，它可以以几种不同的形式释放。此外，不同的物理形态，如分子碘、气溶胶形态碘或有机碘，一旦进入大气，其行为都会有所不同，并且会以不同的速率被去除。日本各地的监测站检测到了这些释放情况，通过这些测量，可以对释放的不同化学形态以及每种形态在环境中的持久性有重要的了解。
