In addition to the hazard of direct exposure to the electron beam you
must be aware of the potential for induced radioactivity in objects near
the path of the beam. The GRWP specifies the requirements for hall
entry after beam shutdown. Typically, a radiation survey is done to
evaluate conditions in the hall. If radiation levels exceed certain
thresholds, then specific signs, postings, and barriers will be
installed by the RCG or ARMSs. In addition, verbal instructions may be
given to personnel in the area regarding access to various locations.
If it is necessary to remove or modify beam line or target chamber
components, or to perform any work in a posted Radiation Area, you must
consult the RCG before beginning work. In many cases a specific RWP
(SRWP) is required for work. SRWPs for many activities will be
available in the Counting House for review. Any item which was in the
hall during beam delivery and needs to be removed from the hall, must be
surveyed by the RCG prior to removal. All hardware, materials, or
components which are waste items should be placed in the large blue
drums available for potentially activated material. The RCG will survey
these items before disposal.
If it becomes necessary to perform work on any piece of equipment in the
hall that may have received a significant dose of direct radiation
you must have it surveyed by a radiation monitor before your work can
begin. This means that all work on beamline or target chamber equipment
will involve a radiation survey.
If it is necessary to remove any item from the hall after or during a
running period it should be surveyed first. All components must be
surveyed and released by a radiation officer before they can be removed
from the hall.
