Extrapolating from the Q&A's (NUREG/CR-6204) supplied by the NRC for the "new"
Part 20: As previously brought up, the TEDE is the sum of the DDE and the CEDE
- the dose to the skin and the dose to the extremeties are separate doses with
their own limits and are NOT part of the TEDE.

Further esoteric but important info about skin and extremity doses: The
shallow dose equivalent to the skin OR to ANY extremity can not exceed 50 Rem.
The skin of the extremity is not considered in the shallow-dose equivalent
limit to the skin of the whole body....

Furthermore... since the limit is to ANY extremity, the worker may receive a
shallow-dose equivalent to each of the four extremities separately - they are
not summed to determine an overexposure. (As long as any one extremity did
not receive > 50 rem.
