Those responsible for the rapid and reliable detection of airborne plutonium should
consider the following workplace characteristics in evaluating monitoring systems
and working environments (Mishima et al., 1988):
-- The airflow patterns and airborne transport of plutonium in the workplace
-- The location of personnel within the workplace during various processing
-- The location at which the airborne plutonium sample should be intercepted
before the sample is inhaled by workers
-- The ability of the system to transport an undistorted sample to the collection
media or measurement device
-- The collection and retention efficiency of the collection medium
-- The efficiency of the measurement device in measuring the plutonium collected
and differentiating the plutonium from other materials present
-- The accuracy and reliability of the system.
Guidance for each area listed above is provided in Mishima et al. (1988).
SURFACE CONTAMINATION CONTROL
Controlling plutonium surface contamination is essential because it may easily be
resuspended in air and/or transferred to other surfaces. The following elements are
important for controlling surface contamination: keeping plant surfaces clean; monitoring,
reporting, and tracking contamination levels; and establishing appropriate control zones
with limits and action levels for those zones.
