1 Exposure scenario titles consist of release activity followed by exposure calculation abbreviation. 

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release 

activity labels. Multiple release activities are combined in one exposure scenario if their releases occur at 

same location. 
1/9/13 Page of 

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and 

Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure 

scenario. CC is the aquatic concentration of concern. 

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily 

streamflow of the seven consecutive days of lowest flow within a ten year period.
