Responsibilities of the worker when using an RWP

Workers must read and comply with the RWP requirements.

Workers must acknowledge they have read, understood, and agreed to comply with

the RWP prior to entering the area and after any revision to the RWP. This is done

by signature or through electronic means.

Radiological Control or a supervisor should be contacted prior to work if the RWP

appears to be incorrect or is difficult to understand.

Do not make substitutions for specified requirements.

Report to Radiological Control personnel if radiological controls are not adequate or

are not being followed.

B. Radiological Postings

Radiological postings are used to:

Alert personnel to the presence of radiation and radioactive materials.

Aid in minimizing personnel dose.

Prevent the spread of contamination.

In addition, 10 CFR 835, Subpart F, specifies requirements for personnel entry controls

for HR and VHR Areas.

Posting requirements

Areas and materials controlled for radiological purposes will be designated with a

magenta or black standard three-bladed radiological warning symbol (trefoil) on a

yellow background.

Fixed barriers such as walls, rope, tape, or chain will designate the boundaries of

posted areas. Where possible, the barriers will be yellow and magenta in color.

The barriers should be placed to clearly mark the boundary of the radiological areas.

Entrance points to radiologically controlled areas should have signs or postings stating

the entry requirements, such as "Personnel Dosimeters, RWP and Respirator

Required."

In some cases, more than one radiological condition may be present. The area shall

be posted to include all of the radiological conditions that are present.

In areas of ongoing work activities, the dose rate and contamination levels (or ranges

of each) may be included in postings.
