AMBIENT RADON MEASUREMENT LOCATIONS
This section describes the placement and expectations for data collection for the ambient radon
track etch detectors.
Figure 7.1 and Table 7.1, respectively, show and list the locations of the tack etch detectors. Four
of the locations are air monitoring stations. One of the locations is in Upton.
Data will be collected minimally in quarters: during plant construction, operation, and closure, to
determine ambient radon concentrations at the Upton Project.
