Conduct of Radiological Work
To minimize intakes of radioactive material, smoking, eating, or chewing should not be permitted in contamination,
high contamination, or airborne radioactivity areas. When the potential for personnel heat stress exists, drinking
may be permitted within a contamination area under the following conditions and controls:
The potential for heat stress cannot be reduced by the use of administrative or engineering controls
All drinking is from approved containers or sources
At a minimum, workers' hands and faces are monitored for contamination prior to drinking
Participating workers are monitored as part of the bioassay program
The applicable requirements and controls are described in approved procedures.
343 Logs and Communications
Radiological control personnel should maintain logs to document radiological occurrences, status of work activities,
and other relevant information.
During continuous or extended daily operations, oncoming radiological control personnel should review logs and
receive a turnover briefing from the personnel they are relieving.
Communication systems required by the radiological work permit or technical work document should be checked for
operability before being brought into the work area and periodically during work.
Workers should keep radiological control personnel informe d of the status of work activities that affect radiological
344 Review of Work in Progress
As part of their normal work review, both radiological control and work supervisors should periodically review
ongoing jobs to ensure prescribed ra diological controls are being implemented.
Radiological control personnel should conduct frequent tours of the workplace to review the adequacy of
radiological work practices, posting, and area controls.
During the performance of jobs for which a p re-job dose estimate was made, the radiological control organization, in
cooperation with line management, should periodically monitor collective dose accumulation and compare it with the
pre-job dose estimate. Differences should be reviewed to identify causes and assess the need for corrective
345 Stop Radiological Work Authority
Radiological control technicians and their supervisors, line supervision, and any worker through their supervisor
shall have the authority and responsibility to stop radiological work activities for any of the following reasons [see
Inadequate radiological controls
Radiological controls not being implemented
Radiological control hold point not being satisfied.
Stop radiological work authority should be exercised in a justifiable and responsible manner.
