Ultravoilet Sterilizers

Virus is supposed to be inactive on surfaces other than the specific human body parts. Virus is not alive and so cannot be killed in the sense in which it is applied to bacteria, Bacteria & fungus grows on most surfaces, while virus does not grow its colonies other than on the host living cells of a human or animal. In-fact the Pathogen Kill rate is highest for Virus, because they have a very small and thin protective coating, which UVC can penetrate and disrupt the RNA of the virus. Both DNA and RNA have a peak absorption of UVC at 265 nm. The UVC disrupts particularly the Thymine base of the DNA/RNA. If there are a few disruptions, the pathogen is often able to repair the same, and get back to its old replicating, infecting self. However if the Thymine disruptions are very many, the RNA/DNA is irreparably damaged and the Pathogen is permanently disabled as it cannot replicate itself. This is called Inactivating the Virus, Not killing as the Virus is simply a self-replicating code, not a living organism. Incase of bacteria, the pathogens are much larger, more complex and a complete living system. These are more difficult to kill, as their DNA is isolated in a double Walled structure, so need much higher UVC Energy. But they too are destroyed / inactivated by UVC energy. However Bacterial Spores are far more difficult to damage as they are in a very hardy casing, so need much more energy/ longer time. Virus and pathogen Fungus also have DNA are large systems, but are also destroyed by UVC light, although since their sizes are large, the need more energy.
