Question 111: Section 20.105 (a) of 10 CFR Part 20
provides for Commission authorization of radiation levels
in unrestricted areas based on a criterion of 500 millirems
in one year to an individual in such areas. Does such an
authorization for radiation levels in an unrestricted area
excess of 100 millirems in a year continue under 10 CFR
20.1301 (c)? In other words is this considered an
"exemption" as covered in 10 CFR 20.1008 (d)?
Answer: No and No. The nature of the information
requested under 20.1301 (c) is different from that
requested under 20.105 (a) in that 20.1301 (c) requires a
demonstration of need for the proposed dose limit and
procedures for maintaining doses ALARA. It may be
appropriate for an applicant to refer to information
submitted under 20.105 (a) as part of an application
submitted under 10.1301 (c). (References: 10 CFR 20.1301
(c), 10 CFR 20.1008 (d), and 20.105 (a))
