The National Library of Medicine has compiled a fantastic resource highlighting the dose rates required to inactivate various pathogens. It covers the benefits of 200nm-230nm vs. traditional 254nm technology.
The unique highlight of this article is in the conclusion section. Of all frequencies, 222nm has the most potential to eliminate various pathogens. The article specifically notes that if you can reach 100 mj/cm2, you can be effective against almost any pathogen, and that's now possible with the new skin (479mj/cm2) and eye (160 mj/cm2) Threshold Value Limits!
