Figure 5.

Log loss of MS2 bacteriophage as a function of time on PTFE disks in a low-dew-point environment. Time in hours is shown on the x axis and the log loss of MS2 is shown on the y axis. Two trendlines are displayed, indicating the log loss of MS2 as a function of time with and without exposure to BL₄₀₅ irradiance. The shaded region between the two trendlines represents the viricidal effect of BL₄₀₅ on PTFE disks in low-dew-point environments. The microbial detection limit for these experiments is shown as a line at the top of the figure.
