Question 116: 10 CFR 20.2101 (b) requires the licensee to

make a clear distinction among the dose quantities entered

on the records and gives examples of the following

different dose quantities: total effective dose

equivalent, shallow dose equivalent, eye dose equivalent,

deep dose equivalent, committed effective dose equivalent.

Does this mean (for example) that the dose rates measured

during surveys of external radiation fields must be

recorded in terms of one of these dose quantities or (as

another example) that the results of air sampling must be

recorded in terms of one of these quantities?

Answer: No. The examples given refer to dose quantities

used for doses to individuals, not to dose (or activity)

quantities used in surveys of areas. (Reference: 10 CFR
