 I've seen them used in the cavity, sump, high dose valves, etc. Lead blankets, water blocks, poly blocks all work.

Um, just for my mental clarity, you mean those "safe-spots"  they have all over chernobyl or is it more akin to temp shielding?

Yes, it's like the temporary shielding that you see during outages, but it doesn't have to be temporary.  The idea is to shield an area, rather than a source. Think of a walkway near a bank of valves or heat exchangers.  Instead of piling shielding on all those valves, you just build a wall between them and the walkway.
It's more effective and takes less shielding.

Cool, thanks. Where does the term "shadow" come from then? Kind of strange moniker for it really O.o.  Splittin hairs at this point though. :p
