Re: La Hague1
With respect to organ doses vs. body size, visceral organs are nearer
the surface in small people, e.g., kids. Thus, the ratio of organ
dose to skin entry dose is greater in children. For a given skin dose
(or, if you are from the old school, exposure) and quality of external
radiation, the dose to visceral organs is greater in smaller bodies.
This obviously has no meaning when we consider uniform whole-body
dose. However, it is a factor in real-world exposures, when the dose
is not uniform throughout.
