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, Ch. 1. (DOE, 2004). 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 18 topics addressed

in DOE Order 5480.19, Ch. 2 (DOE, 2001c) should be subject to both internal self-

assessment and external auditing to assure effective implementation of their

requirements. Any deficiencies identified should be documented and corrective

actions aggressively pursued and tracked to completion. The self-assessment and

audit process should include conducting trend analyses and root cause evaluations

of deficiencies and communication of results throughout the organization.
