The cell nucleus of microorganisms (bacteria, viruses and fungi) contains thymine, the chemical component of DNA / RNA.

This component absorbs UV-C radiation at 253.7 nm and changes to such an extent (thymine dimer formation) that the cell is no longer able to survive or multiply.

• UV-C (253.7 nm) penetrates the cell wall of the microorganism

• High energy UV-C photons are absorbed by DNA / RNA cell proteins

• UV-C damages the structure of the protein, causing metabolic disorders

• DNA / RNA is chemically altered, so organisms cannot replicate

• Organisms are not able to metabolise and replicate, they CANNOT cause disease or damage to other organisms
