The Big Thirst: How Is Japan's Fukushima Nuclear Plant Making "Radioactive" Water?

The Big Thirst: How Is Japan's Fukushima Nuclear Plant Making "Radioactive" Water?

But since the water itself is not radioactive, it can be cleaned. Water, in fact, is one of the few substances that can be de-radiated. The radiation can be taken from it by simply filtering--basic filtering of the dirt, and more sophisticated filtering, using something called ion-exchange beds, to get both suspended dirty and dissolved substances out. It's a bit more complicated than running the stuff from your tap through a Brita filter. But it's also not that different. In fact, every nuclear reactor does precisely that kind of filtering all the time--nuclear plants routinely super-clean their reactor water, precisely to prevent any debris from starting to circulate (corrosion from pipes or valves, for instance) that would quickly become radioactive.
