Summary of key quantitative metrics for measured stray radiation air kerma values at all 63 spatial locations within the Significant Zone of Occupancy (SZO). A timer setting of 1.0 sec was used for all device measurements, implying the X-ray output is not constant across the devices. Normalization is required to directly compare the measured stray radiation between devices.
