Radiological Control
Conduct of Radiological Work

PART 4 Radiological Work Controls
341 General
1.
Radiological work activities shall be conducted as specified by the controlling written authorization [see
835.501(d)].
2.
Prerequisite conditions, such as tag-outs and system isolation, should be verified in accordance with the technical
work documents before work is initiated.
342 Work Conduct and Practices
1.
Contamination levels caused by ongoing work should be monitored and maintained ALARA. Work should be
curtailed and decontamination performed at preestablished levels, taking into account worker exposure.
2.
Tools and equipment should be inspected to verify operability before being brought into contamination, high
contamination, or airborne radioactivity areas.
3.
The use of radiologically clean tools or equipment in contamination, high contamination, or airborne radioactivity
areas should be minimized by the implementation of a contaminated tool crib in accordance with Article 442.5.
When such use is necessary, tools or equipment with complex or inaccessible areas should be wrapped or sleeved to
minimize contamination.
4.
Engineering controls, such as containment devices, portable or auxiliary ventilation, and temporary shielding,
should be installed in accordance with the technical work documents and inspected prior to use.
5.
The identity of components and systems should be verified prior to work.
6.
Work activities and shift changes should be scheduled to prevent idle time in radiological areas.
7.
Where practicable, parts and components should be removed to areas with lower radiological hazards to perform
work.
8.
Upon identification of radiological concerns, such as inappropriate work controls or procedural deficiencies,
workers should immediately report the concern to line supervision or the radiological control organization. If
appropriate to control individual exposure to radiological hazards, the affected individuals should exit the
radiological area until these issues are resolved and appropriate controls have been instituted.
9.
Requirements for area cleanup should be included in technical work documents. Work activities should not be
considered complete until support material and equipment have been removed and the area has been returned to at
least pre-work status.
