Used for In-Plant Plutonium Monitoring (ANSI, 1980a). These clean
areas should be maintained below the surface contamination levels cited
in 10 CFR 835 (DOE, 1998a).
Regardless of the general radiation safety knowledge of visitors to a plutonium
facility, they should be escorted at all times when they go into the posted areas of
the plant. In addition, before going into such an area, they should be given a
general orientation to the facility radiation protection program and informed about
the potential radiation conditions in the areas where they will be going. They also
should be provided with the same protective devices worn by facility personnel
engaged in similar activities.
Visitors with a demonstrated need to enter the following areas may be allowed
access if such access is controlled with a combination of training and the use of
escorts trained for the specific area:
Radiological Buffer Areas
Radiation and High Radiation Areas
Radioactive Material Areas
Guidance for training for visitors is provided in the standard, Radiological Control,
Ch. 1.(DOE, 2004), Article 622:
-- Persons under 18 years of age should not be permitted to enter Radiation Areas
or Contamination Areas without the approval of the Radiological Protection
-- Area entry requirements and access restrictions for visitors should be in
accordance with established facility procedures.
-- Individuals, visitors included, shall (10 CFR 835.502(b)) be prevented from
entering Very High Radiation Areas when dose rates are in excess of the
posting requirements of 10 CFR 835.603(c), and visitors should be prohibited
In addition the following is recommended:
All facility personnel serving as a qualified escort should ensure that each visitor
under his/her cognizance completes a facility radiological visitor form. The
qualified escort should also sign the visitor form and complete it as appropriate.
