Re: Pronunciations of SI prefixes: kilo and giga; Unit Plurals

Ron:
You're correct when you say "I note that the dose equivalent quantities
as expressed in rem and Sv are not necessarily numerically equal to
J/kg."
But, the fact remains that they are DEFINED as being equal to 1 j/kg.
As is the Gy.
I maintain that measurements should be made in physical units; flux as a
function of energy. That way everyone would always understand what the
numbers mean.
We keep trying to create a dosimetric system that is proportional to
risk. We've gone from r to rad to rem to Gy to Sv and we're still no
closer. As you say, "dose equivalent is not a physical quantity per se."
Until we make measurements in physical units we're just spinning our
wheels.
Best wishes,
Wade
