当反应堆内的水比通常情况下的放射性高得多，而且处于高压之下的话，反应堆的强烈冲击可能会成为一个更加严重的问题。

Backlash from the reactor is likely to be an even bigger problem when the water inside the reactor is much more radioactive than usual and is under extremely high pressure.

1946年到1958年，在马绍尔群岛北部进行了67次核试验，释放出的放射性碘造成的污染据说比1986年切尔诺贝利核灾难带来的污染严重150倍。

The 67 tests conducted in the northern Marshalls between 1946 and 1958 released radioactive iodine said to be 150 times worse than the contamination from the nuclear disaster at Chernobyl in 1986.

As carefully as people work with radioactivity here, and using often much, much safer radioactive materials than radium bromide, and using them, and special hoods, and having special procedures, they still do a lot of checking with these Geiger counters to make sure everything's safe.

虽然在这里人们,用放射性物质都非常的小心，而且通常用的材料放射性,都比溴化镭要小得多，并且用的时候,都用特殊的容器,特殊的操作过程,但我们平时仍会用。
