The highest fine for failing to safely deal with radioactive substances is about $700.

未能安全处理放射性物质的最高罚款约为700美元。

Volunteers would be injected with a radioactive substance that links up to a protein in the vesicles, or storage containers, used by synapses.

志愿者会被注射一种放射性物质，与囊泡中的蛋白质或突触使用的存储容器相连接。

But it emerged in 2018 that 70 percent of the tanks also contained levels of other radioactive substances that were higher than legal limits.

For example, there was the leaking of highly radioactive water in 2016, and strontium and other radioactive substances were found to have exceeded normal standard in 2018.

例如，2016 年发生了高放射性水泄漏，2018 年发现锶等放射性物质超标。

Melted nuclear fuel debris inside the damaged reactors is being cooled by pumped-in water, which comes into contact with a toxic cocktail of radioactive substances known as radionuclides.

受损反应堆内的熔化核燃料残渣通过注入的水进行冷却，这些水与一系列有毒的放射性物质（即放射性核素）接触。

The Fukushima nuclear accident which took place 12 years ago was a major catastrophe that already caused the leakage of large amounts of radioactive substances into the ocean.

12 年前发生的福岛核事故是一场重大灾难，已经导致大量放射性物质泄漏到海洋中。

For 10 days, a large amount of radioactive substances pervaded the air, most of it falling as dust into nearby areas, but smaller particles spread far and wide carried by the wind.

连续十天，空气中弥漫着大量的放射性物质，大部分以尘埃的形式散落到附近地区，但小颗粒在风的作用下传播得更远。
