Temporary Shielding

Design shielding to include stress considerations

Control installation and removal by written procedure

Inspect after installation

Conduct periodic radiation surveys

Prevent damage caused by weight of heavy temporary shielding

Balance radiation exposure received in installation against exposure saved by installation

Shield travel routes

Shield components with abnormally high radiation levels early in the maintenance period

Shield position(s) occupied by worker

Perform directional surveys to improve design of shielding by locating source of radiation

Use mock-ups to plan temporary shielding design and installation

Consider use of water-filled shielding

Rehearsing and Briefing

Rehearse

Use mock-ups duplicating working conditions

Use photographs and videotapes

Conduct briefings of workers in accordance with Article 324

Performing Work

Comply with technical work documents and RWPs

Post radiation levels

Keep excess personnel out of radiation areas

Control radiation exposure while controlling exposure to other hazards

Supervisors and workers keep track of radiation exposure

Compare actual dose against pre-job estimates

Workers assist in radiation and radioactivity measurements

Delegate radiological control monitoring responsibilities

Evaluate the size of the work crew as work progresses

Reevaluate methods used to control radiation doses

Compare actual collective dose against pre-job estimate

Coordinate personnel at the job site to reduce non-productive time
