I'm being given a personal FAR-UVC device of 10 watts, and I want to test its efficacy on sars-cov-2.<p>My background is in QA, and also now patient advocacy. I am disabled and I'm part of a larger disabled community, and we are trying to figure out how to protect ourselves during medical appointments in unmasked facilities.<p>I've purchased some dosimeter cards from Intellego, but I'm having trouble figuring out exactly how to use them to figure out time / efficacy of disinfection.<p>One card changes color at 3, 6, 10, 20, and 30 mj/cm2. But I'm still seeing conflicting info in the research about exactly what intensity works to reduce sars-cov-2. Also there is a duration issue. The card shows when I've reached that amount of exposure but not the other question of duration (like 30 seconds at 3 mj/cm2).<p>I do not have $3,000 for a digital dosimeter.<p>Suggestions welcome!
