Update radioactivity-related units from http://physics.nist.gov/cuu/Units/. The prior definition of sievert was, as far as I can tell, entirely wrong. Caution: while "gray" and "sievert" have the same dimensionality, they're not interchangeable -- you need to multiply by a fudge factor that varies depending on the type of radiation and the tissue it's affecting. (Dimensional analysis is often not a substitute for knowing what you're doing.) It would be nice if units had a way to warn users when they're trying to do something that doesn't make sense, since there are lots of ways to do so, but it doesn't, and it wouldn't be easy to arrange in the general case.
