Question 144: When will licensees be permitted to use

weighting factors other than one to determine and record

external whole body dose (effective dose equivalent from

external sources) as the occupational dose of record?

Answer: After the NRC has received and approved an

application for the use of weighting factors (Wt) other

than one for obtaining the effective dose equivalent. See

the discussion of the comment on the use of effective dose

equivalent for external exposure in the Statement of

Considerations (56 FR 23368, third column and 23369, first

column). The response to the comment concludes with the

statement that "The use of other weighting factors for

external exposure may be approved on a case-by-case basis

upon request to the NRC." (Reference: 10 CFR 20.1003).
