有意思的是，电厂里的本底辐射水平低于莫斯科中心的本底辐射水平。

It is an interesting fact that background radiation level in the power plant is lower than in the center of Moscow.

从生物机理上说，我们可能已经习惯了这种本底辐射。

Possibly we are accustomed, biologically speaking, to this background radiation.

其他国家迄今测量到的辐射程度，远低于大多数人每天都会受到的本底辐射水平。

Radiation levels measured to date in other countries are far below the level of background radiation that most people are exposed to in every day circumstances.
