What is UV light?

Ultraviolet light was discovered by the German physicist J. W. Ritter, back in 1801. It is an electromagnetic radiation with wavelength from 10 nm – 400 nm. In the range of the EM spectrum, it falls between visible light and X-radiation. There are three types according to the amount of emitted energy – A, B and C. Both germicidal and bactericidal radiation is a relatively short segment of the light spectrum with wavelength of 253,7 nm. 


How is UV light produced?

In artificial settings, UV light is produced using low pressure discharge tubes filled with mercury vapor or mixtures of mercury and an inert gas. The tube is made of silicone glass to let through radiation with lower wavelengths (since the regular glass doesn’t let UV light through). A glow discharge emitting photons is lit in the tube by the electrodes. The wavelength of the radiation produced depends on the type of gas and the parameters of an electric discharge.  


How does UV disinfection work?

Exposure to UV light causes physiological changes in living organisms (bacteria, moulds, mites, but also people, animals and plants). These changes consist in decay of chemical structures of the DNA/RNA and this, in turn, prevents the chance of reconstruction and transfer of genetic information. Organism affected in this way is not able to reproduce and dies. From the microbiological point of view, the exposed place becomes technically sterile.


What is a germicidal lamp?

There are two main types of germicidal lamps – direct and indirect.

Direct lamps

They serve for a direct exposure of the place or surface one wishes to disinfect. They are highly effective and it is possible to repeat the process many times. Another advantage is that the time needed for the exposure of air and surfaces is relatively short. However, as the radiation has lethal impact on all living organisms, no person, animal or plant can be present in the room during irradiation.

Indirect lamps

Their functions outweigh the disadvantages of the direct lamps. The way disinfection works is the same as with the direct lamps, but it’s the air flowing through an enclosed space that´s being irradiated. Unwanted microorganisms might be present in its aerosol particles and these are exposed to a high dosage of the germicidal radiation. When the process is finished, the air is blown back into the room – and that’s why an enclosed lamp can be safely used even in presence of people.

The legislature of Slovak Republic obligates every medical facility to use germicidal lamps. More information is available in the regulation of Ministry of Health of Slovak Republic no. 09812/2008-OL from 10th of September 2008 about the minimal personal and technical equipment required in certain types of medical facilities.
