|  Radiological Assessor Training
DOE-HDBK-1141-2001
Student's Guide
Different devices may be used to confine and
control radioactive material. The selection of the
appropriate device will depend on the quantity of
material, its form, and the operations to be
performed.
Fume hoods may be used for some operations
with plutonium, depending on the quantity and
dispersability of the material. In general,
plutonium fume hood operations shall be limited
to wet chemistry processes and less than 100 mg
of plutonium.
Higher levels of plutonium are generally handled
in glove boxes. Care should be taken in the
design of the glove box to ensure confinement of
the material and any fire.
Ventilation may also be employed to confine
plutonium, although it usually is used in
conjunction with other measures.
H. Personnel protection
Workers in plutonium facilities need to be
appropriately trained on the hazards. DOE has
developed Radiological Safety Training for
Plutonium Facilities, DOE-HDBK-1145-2001.
This document provides DOE's guidance on
expectations for training of plutonium workers.
The use of personal air sampling programs should
be considered to monitor individual workers for
exposure to airborne plutonium. Section 4.4.4 of
DOE-STD-1121-98, Internal Dosimetry, discusses
use of breathing zone or personal air monitoring
when there is a technology shortfall (i.e., the
derived investigation level is less than the
minimum detectable activity). Technology
shortfalls are common for routine plutonium
bioassay programs.
