Prediction of Aerosol Viability From Experiments on Surfaces (PAVES): Program Summary Report
Abstract
This report describes the Prediction of Aerosol Viability from Experiments on Surfaces (PAVES) program after completion of its third year. PAVES includes both experimental and computational modeling tasks. Experimental determination of bacterial particle viability loss (biological decay) due to radiation exposure forms the main body of work. The research embodies two parallel investigations on particles comprising Bacillus anthracis spores (Sterne strain). One study exposes spores while suspended as aerosols and the other after deposition onto surfaces. Both use two commercially available ultraviolet (UV) radiation sources: a low-pressure mercury vapor discharge germicidal lamp and a solar simulator (SS) lamp. Survival fractions are determined from plating assays as a function of radiation exposure time (dose) and particle size. This report presents the final core experimental data, a comprehensive description of the program, and a comparative analysis between aerosol- and surface-exposed radiation effects on spore viability.
