Seeking Help to Test Far-UVC Device

I&#x27;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&#x27;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&#x27;ve purchased some dosimeter cards from Intellego, but I&#x27;m having trouble figuring out exactly how to use them to figure out time &#x2F; efficacy of disinfection.<p>One card changes color at 3, 6, 10, 20, and 30 mj&#x2F;cm2. But I&#x27;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&#x27;ve reached that amount of exposure but not the other question of duration (like 30 seconds at 3 mj&#x2F;cm2).<p>I do not have $3,000 for a digital dosimeter.<p>Suggestions welcome!
