, which would appear to exclude the effective dose to the skin and eyes from non-penetrating radiation such as beta.
These surface doses are included in the NRC's shallow dose equivalent, along with contributions from penetrating (gamma) radiation.
Regulatory limits are imposed on the TEDE for occupationally exposed individuals and members of the general public.
