Composite Worker Soil 2-D Alternate External Exposure Analysis Graphic (under development) and Supporting Text


Composite Worker. This is a long-term receptor exposed during the work day who is a full time employee working on-site and who spends most of the workday conducting maintenance activities outdoors. The activities for this receptor (e.g., moderate digging, landscaping) typically involve on-site exposures to surface soils.

This analysis is designed to look at external exposure from contamination of different area sizes. Areas considered are 10, 50, 100, 500, 1000, 2000, 5000 and 10,000 square meters. Isotope-specific area correction factor (ACF) were developed for this analysis.
