It has been demonstrated that many microorganisms can be inactivated by continuous UV-C radiation. UV-C radiation is absorbed by DNA and RNA, causing changes in their structures and preventing their replication. The radiation dose required to achieve a microbial load reduction depends not only on the particular microorganism, but also on additional factors like radiation intensity (power) of the emitting source, distance between emitting source and surface, and time of exposure. Furthermore, surfaces that only receive radiation by reflection, get lower doses that may not be sufficient to incativate the pathogenic microorganisms present. Considering all this, it is of utmost importance to control that all surfaces to be disinfected, receive the minimum radiation dose required.

CD63-ST/ Chemical Indicator For monitoring disinfection processes of surfaces by means of Quaternary Ammonium. It has been proved that many microorganisms may be inactivated by using quaternary ammonium salts (QUATS). These cationic surfactants interfere with the functions of the bacterial cell membranes and the lipid capsid of the virus, releasing the contents outside the cell, thus rendering them inactive. The minimum doses of quaternary ammonium needed to achieve a certain reduction in the microbial charge depends not only on the particular microorganism but also on additional factors such as the dirt present in the environment, the temperature, the humidity and time of exposure to the chemical agent. Because of the aforesaid, it is of utmost importance to check that all the surfaces to be disinfected receive the same doses of the disinfectant agent.
