Ultraviolet rays (100-400 nm) are a type of naturally occurring radiation
generated by the sun but only partially found on Earth due to the
ozone layer in the atmosphere acting as a filter with a percentage of
attenuation up to 100% for wavelengths shorter than UV-C.
By ultraviolet rays we mean electromagnetic waves which are divided
into three main wavelength ranges:
- UV-A (315-400 nm) with tanning properties;
- UV-B (280-315 nm) with therapeutic and vitamin synthesis properties
"D";
- UV-C (100-280 nm) with germicidal properties.
UV-C rays have the strongest germicidal effect and are most effective
at a wavelength of 265 nm.
The germicidal effect of UV-C radiation extends to viruses, bacteria,
spores, mould fungi and mites. It is mainly due to the destructive effect
exerted by UV-C radiation on their RNA / DNA: in fact, UV-C damages
their genetic makeup, preventing their replication.
Viruses, bacteria, spores, fungi, moulds and mites are all sensitive and
can therefore be eliminated with UV-C rays respect to different energy
doses required.
