[ RadSafe ] bakscatter xray

[Brennan, Mike (DOH)]

If the majority of the energy is delivered to the skin, then wouldn't it
follow that the majority of THAT energy is delivered to the outer layer
or the skin; the layer of dead skin cells?  If the claim is that the
radiation penetrates the dead layer, but is then deposited in the living
tissue, I would think that there should be some support for that.

(28keV).The majority of their energy is delivered to the skin and the 
Underlying tissue. Thus, while the dose would be safe if it were
distributed 
throughout the volume of the entire body, the dose to the skin may be 
dangerously high.
