You can aleways look them up in the regulations:



§ 20.1003 Definitions.

As used in this part:



Deep dose equivalent (Hd), which applies to the external whole-body 

exposure, is the dose equivalent at a tissue depth of 1 centimeter 

(1000 mg/cm2).



Eye dose equivalent applies to the external exposure of the lens of 

the eye and is taken as the dose equivalent at a tissue depth of 0.3 

centimeter (300 mg/cm2).



Shallow dose equivalent (HS) applies to the external exposure of the 

skin or an extremity and is taken as the dose equivalent at a tissue 

depth of 0.007 centimeter (7 mg/cm2) averaged over an area 1 square 

centimeter.
