Germicidal radiation UVC 253.7 nm

Ultraviolet radiation

Ultraviolet radiation is optical, electromagnetic radiation with a wavelength of 100 nm to 1mm.

Ultraviolet radiation with a wavelength of 100 nm to 400 nm can be divided into:

  • UVA 315 nm to 400 nm
  • UVB 280 nm to 315 nm
  • UVC 100 nm to 280 nm

Germicidal radiation - UVC wavelength of 253.7 nm is invisible. This radiation (in the UVC spectrum) causes mortality of microorganisms in a way that their DNA is distorted and hence they are destructed. Blue light produced by germicidal lamps is only a byproduct. This part of the spectrum is not antiseptic. Germicidal radiation does not pass through matt, non-transparent materials, neither through glass, which creates a reliable barrier for it. This radiation only passes through quartz glass and special Teflon foils.
