This presentation will summarize how previous studies characterized upper room GUV (UR-GUV) installations, focusing on their radiometric properties and dosing criteria. Across these studies, we examine the consistency in reported properties for potentials to inform the design of future UR-GUV installations. The questions to be answered are: 1) are the reported properties sufficient to inform the selection and sizing of UR-GUV systems for different applications? And 2) what measurements should be reported to promote consistency and comparability between studies?
