DOE-HDBK-1141-2001
Instructor's Guide
If large quantities of uranium hexafluoride are
present, appropriate neutron survey instruments
should be available to measure the neutron
If the facility contains enriched uranium and/or
Uranium-233, appropriate criticality safety alarm
systems shall be in place and appropriate
neutron and gamma survey instruments
available.
Continuous air monitors (CAMs), sample
extraction lines that go to CAMs, and continuous
radiation dose monitors should be placed
outside glove boxes and fume hoods.
Show OT 6.6.
B. Survey Techniques
Monitoring practices include, but are not limited
to, the following:
Contamination surveys of the workplace
Release surveys
External exposure surveys
Airborne contamination surveys
Routine surveillance by a Radiological
Control Technician
All work areas must be monitored for
contamination levels on a regularly scheduled
basis. The frequency of such surveys will
depend on the potential for dispensability of the
radioactive material. During these routine
surveys, all work enclosures, work surfaces,
floors, and equipment within the workplace
should be surveyed.
Show OT 6.7.
C. Workplace characterization
At the time a program is established,
measurements of external dose should be made
