Student's Guide
1. Containment
Because plutonium is of particular concern if
inhaled, special precautions are taken to
avoid airborne contamination. There are
many different types of containments that,
when used in conjunction with ventilation,
help prevent the loss of material and thus
minimize dose to the workers.
Gloveboxes are almost always used when
handling plutonium in a dispersible form.
However, properly vented hoods are
acceptable for handling the very small
quantities used in a research laboratory.
Proper hood design is critical for plutonium
and only very small quantities should be
used.
Gloveboxes, tanks, and piping are examples
of "primary containments," because there
are no system openings. Gloveboxes have
ports with long plastic sleeves attached that
allow material to be "sealed in" or "sealed
out" from the glovebox without breaching the
containment.
Types of equipment such as fumehoods are
"primary confinements," since they are the
barrier closest to the source. Primary
barriers require good ventilation to maintain
contamination control. Do not insert your
hands into a primary barrier unless you
have been trained and authorized to do
so.
