Figure 1:
Flowchart of selection of badge entries used to report monthly and annual dose values. The numbers reported are the sum of all years, 2009, 2012, and 2015. The lower limit of detection (LOD) is 0.02 mSv. Entries below the dotted line are judged to provide informative data on occupational doses within the fluoroscopic suite; however, not all of these entries were included in our analysis of monthly or annual doses either because the workers were not on a monthly exchange protocol or they lacked a full year of reliable doses, respectively. HE = effective dose equivalent.
