Guide of Good Practices for Occupational Radiological Protection in Plutonium Facilities

3.9.2 Posting and Labeling

The requirements for posting and labeling of working areas because of the presence, or

potential presence, of radiation and/or radioactive material are specified in 10 CFR 835,

Subpart G (DOE, 1998a). Guidance in implementing the regulatory requirements can be

found in G 441.1-10, Implementation Guide. Posting and Labeling for Radiological Control

(DOE, 1999d), and the standard, Radiological Control (DOE, 1999a). Conformance of

conduct of operations requirements should assure a reasonable degree of uniformity in the

posting and the signs used, as well as verifying that operator aids and other posted

information do not interfere with necessary radiological posting. It is necessary to formally

review posting of radiological areas in the same manner that the posting of operating aids is

reviewed, in conformance with DOE Order 5480.19, Ch. 2 (DOE, 2001c).

3.9.3 Calibration of Instruments

The status of installed and portable radiological instruments should be well known and

appropriate to the use. (Calibration of radiological instruments is discussed in Section

3.5.2.)

"Ownership" of installed radiological dose rate and airborne contamination monitoring

instrumentation should be well known and the responsibility and authority for calibration,

repair, and notification clearly established. Because such information is often used by more

than one group, formal notification procedures should be established to cover those times

when the instrument is out of service or beyond the required calibration schedule.

Configuration control and quality assurance requirements for installed systems should be

established commensurate with their safety significance.

For portable instrumentation, conduct of operations requirements are normally built into the

routine calibration and survey program. Functional checks are routinely made to verify

calibration, instruments are checked to assure that they are within the calibration period, and

survey procedures require identification of the instruments used so that if a problem is later

found, measurements can be repeated.

3.9.4 Audits

Conduct of operations does not, in itself, contain requirements on auditing. Inspections,

audits, reviews, investigations, and self-assessments are part of the checks and balances

needed in an operating program. Auditing is one of the many tools that line management

has at its disposal to identify problems. Regulation 10 CFR 835.102 requires internal audits

of all functional elements of the radiation protection program no less frequently than every 3

years. These audits are to include program content and implementation.. Each one of the
