Principle for UV sterilization
 
All forms of life known on the earth exist on the basis of DNA and RNA for reproduction and existence. DNA and RNA are both composed of 4 kinds of chemical substance units.
A--Adenine
T--Thymine
C--Cytosine
G--Guanine (the basic component for the nucleic acid)
In time of cell reproduction, the long chains inside DNA are opened when Unit A in each chain will look for and connect with Unit T. Each long chain can reproduce an identical chain to the chain freshly split, restore the complete DNA before splitting and serve as the foundation for the new-borne cells. However, the ultraviolet at a wave length of 240-270nm is able to break the capacity of DNA to produced protein and reproduction. Once the DNA and RNA of bacteria and viruses are damaged, their capacity to produce protein and reproduction are both lost. As the bacteria and viruses usually have a very short life cycle, those will soon perish that cannot reproduce.
The effective of UV sterilization is often expressed in killing ratio, e.g., 99.9%. Namely, 99.9% of the original bacteria have been killed and only 0.1% exists, or, 1/1 000 has survived. As 1000 is the 3 in 103 or in log, it is habitually to express the killing ratio with 310g. The killing ratio of ultraviolet depends on two factors: 1, ultraviolet intensity (I); and 2, irradiation time (T).
