Module 104 Internal Dose Control
Monitoring for airborne contamination can take several forms:
long-term, low-volume air samples that provide an average of the
airborne concentration over a given time;
short-duration, high-volume air samples taken in the breathing zone of
a worker during work activities likely to generate airborne
contamination;
low-volume (about 2 liters per minute) breathing zone samples from
personal air monitors; and [Note: A liter is approximately the same
volume as a quart. Use the concept of a 2-liter soda bottle to describe
the quantity.]
continuous air monitors that track airborne contamination levels over
time and can be set to alarm if a specified level is reached.
It is important that air samples represent the actual airborne contamination
levels breathed by the worker so that accurate intakes may be estimated.
Air monitoring is also used to detect loss of containment. It is important to
ensure sample volumes and methods allow detection of airborne
contamination levels below the level of concern.

Minimization of Contamination Areas
Loose contamination on work surfaces can result in contamination of
shoes, clothing, and skin and thereby result in the potential for tracking of
contamination into uncontrolled areas.
