A good reason to wash your hands frequently.

  I wonder if there were UV hand "washers" all over the place if that would help. If they had the UV hand driers in the restrooms as well as UV baths around the entrances to the xray scanners, such that everyones plastic tub that entered the xray machine was also UV'd as it went through... (Although I dont know how long it would have to be under UV to impact....)

    So there are UV devices used to help disinfect rooms, and there's a lot of time needed for killing. And then there's the whole cancer downside...

    You should be able to cut the UV time down to a second or two, before you get problems with the stuff starting to melt from the radiative heat, even if you use a strong fan to cool the surface. This is worst-case, and I do think you can get away without a fan, but there might be edge cases.
