Not correct. "D" in any form is energy _concentration_ (energy per unit mass). 
E & E just play around with it. It doesn't provide energy absorbed (energy per 
unit mass times mass of the biological unit of interest - cell, organism, or
population). Vic Bond and many other serious biologists have pointed this out
for many years. "Dose" in medicine is the quantity, not concentration, eg,
mg/kg. (It makes a difference, eg, concentration is not an additive quantity.
Vic Bond, with Feinendegen, Sondhaus, Weilopolski, and others, have done
standard dimensional analysis that shows the failure of assessing risk by
considering radiation dose as a concentration quantity.) 

Thanks.
