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 Out-of-date RWPs should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).
