Use of Containment Devices
Whenever activities that may generate loose contamination are planned,
consideration should be given to using containment devices to control the
contamination to an area as close to the source as possible. Such devices include
glovebags, gloveboxes, and tents.
c.
Control and Monitoring of Airborne Contamination
Uranium contamination is relatively dense (heavy) so it is not easily stirred up
into the air and quickly settles out when disturbed. Therefore, it is unlikely that
significant airborne contamination will result from normal activities (such as
walking) in areas contaminated with uranium. It is possible for airborne
contamination to result from activity that vigorously disturbs the surface, such as
sweeping, grinding, welding, and direct, high-volume air flow. Failure to control
airborne contamination could result in inhalation of the contamination and
spread of contamination to other areas.
Control of airborne contamination should include:
an evalua tion of a ctiviti es that a re likel y to cause contamin ation to become
airborne,
engineered co ntrols such as installe d or portable ventilation with High
Efficiency Pa rticulate Air filtrat ion systems (HEPA systems) to remove
contamination from the air at a point as close to the source as possible,
physical barriers (e.g., pipes, gloveboxes, etc) and pressure differential zones,
use of alternate work activities or equipment that is less likely to generate
airborne contamination,
air sampling to track airborne contamination levels, and
using respiratory protection to minimize internal dose of the worker.
Monitoring for airborne contamination can take several forms:
