RE: Another question re: dose
Okay,
The terms spelled out are the gray and the sievert. The abbreviations are
Gy and Sv. The names of the persons for whom the units are named are Gray
and Sievert, with capital letters. (One of my pet peeves)
Do not blame SI, or have you forgot about the rad and the rem.

Hi All,
Several comments.
It's Sieverts, not Seiverts, and Grays not Greys.
But above all, something must be wrong when an equation dictates the use
of units!! Orwellian indeed!
Or, maybe - oh god forbid - it's the LNT and its use that are wrong!
:-))
Have a nice weekend,
Fritz
