Re: When does "rem" no longer apply?

["Gibbs, S Julian" <s.julian.gibbs@vanderbilt.edu>]

I suppose that if you want to be totally politically 
correct, the rem (along with rad, roentgen, curie, etc.) 
are now obsolete units.  However, a whole bunch of us 
diehards grew up thinking in these old units; we are having 
much difficulty converting.  I'm trying.  I write (and 
teach) in grays, sieverts, becquerels, etc., but still 
think in the rad, rem, and curie.
Seriously, we Americans are the subject of international 
ridicule because of our refusal to adopt SI units.  I guess 
we have to.  I just wish the powers that be would find 
something better to do than to dream up new units.
