airborne radioactivity areas. The RWPs should also be used to control

entry into radiation and contamination areas and for handling materials

with removable contamination. The RWPs should be initiated by the

work group responsible for the activity. All RWPs should be reviewed

and approved by the radiation protection staff. Radiological Work

Permits are recommended for other radiological work in accordance with

the standard, Radiological Control, Ch. 1. (DOE, 2004). Most plutonium

facilities will use them for all but routine entries into rooms containing

glove-box lines. Guidance for posting of RWPs and for their contents are

contained in the standard, Radiological Control.

Radiological workers should read and understand the applicable RWP

before performing work in a radiological area. The RWPs should be

located at the access point to the applicable radiological work area.

Workers should acknowledge by signature or through electronic means

that they have read, understood, and will comply with the RWP before

they initially enter the area and after changes. Out-of-date RWPs should

be removed.

3.2.2.3

Radiological Surveys and Data Trending

Area monitoring in the workplace shall be routinely performed, as

necessary, to identify and control potential sources of personnel exposure

(10 CFR 835.401(a) (6)). This monitoring should include surveys in

areas that are not ordinarily expected to be contaminated. The program

should define minimum requirements, survey types, and frequencies.

Surveys should be performed at frequencies adequate to identify changes

in posting required or an activity buildup, and to ensure that current

radiological controls are appropriate. The surveys suggested by this

section are minimum recommendations; additional surveys should be

conducted, recorded, and reviewed as necessary to ensure full protection

of personnel.

Contamination surveys should be performed to determine surface

contamination area (SCA) boundaries, the appropriate posting of sources

or areas, and the location and extent of localized contamination.

Contamination surveys should be performed and documented prior to the

start of radiological work, during general work activities at times when

changes in contamination level may occur, and following work to assure

that final radiological conditions are acceptable and documented. See

Munson et al. (1988).
