46. So, the impurities in the water that do become radioactive

are not emitting the correct particle, i.e. neutrons, to induce radioactivity in other materials?

I note that the site you sent me to says this about the PWR:

PWRs keep water under pressure so that it heats, but does not boil. Water from the reactor and the water in the steam generator that is turned into steam never mix. In this way, most of the radioactivity stays in the reactor area.

Not being picky, but I do pay attention to the way government can use, and misuse words, so I am cautious. If "most" of the radiation stays in the reactor, what is found outside the reactor?
