The uv spectrum ranges from 100 nanometers nm to 400 nm.
Germicidal uv lamp spectrum.
Over the last few years germicidal uv light assisted quit the spread of various microorganisms like the flu and other superbugs.
Uv range falls between 100 and 400 nanometers.
In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.
The technology of germicidal lighting is referred to as germicidal uv or guv.
Advantages of germicidal uv.
Ultra violet uv light is invisible to the human eye and is divided into uv a uv b and uv c.
The longer wavelengths uv described below are not produced by germicidal uv lamps.
Safety tips for using germicidal lamps.
Uvgi is used in a variety of applications such as food air and water purification.
Prolonged exposure causes sun burn and could result in unhealthy effects on the.
The covid 19 circumstance is rapidly changing and also it s creating concerns to change for a great deal of us.
Uv can be divided into different ranges with uv germicidal light said to be short wavelength.
However can germicidal uv also deal with the unique coronavirus or covid 19.
They are part of the complete uv spectrum produced by the sun or some specialty lamps.
Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions.
Pathogen kill rate tests show that germicidal uv products kill up to 99 9 of bacteria and viruses when used correctly.
Germicidal lamps emit radiation in the uv c portion of the ultraviolet uv spectrum which includes wavelengths between 100 and 280 nanometers nm.
Ultraviolet uv is a form of electromagnetic radiation with wavelength from 10 nm with a corresponding frequency of approximately 30 phz to 400 nm 750 thz shorter than that of visible light but longer than x rays uv radiation is present in sunlight and constitutes about 10 of the total electromagnetic radiation output from the sun it is also produced by electric arcs and specialized.
Technically the guv spectrum is defined as uv c.
Philips low pressure uv c lamps have their main emission at 254 nm where the action on dna is 85 of the peak.
The lamps are used in a variety of applications where disinfection is the primary concern including air and water purification.
Most solar uv b is absorbed by the ozone layer.
Germicidal uv lamps are extremely effective and have several major advantages.
While the uv c part of the spectrum is an effective killer of covid 19 and similar viruses it must be used carefully to be both effective and safe.
Therefore the water or air that passes through the chamber is exposed to the germicidal uv light and the genetic material of the microorganism is.
Uv b a small but dangerous part of sunlight.
Ultraviolet light is part of the light spectrum landing between x rays on the low end and visible light on the high end.
On top of that bacteria and pathogens cannot become resistant to uv like they can certain antibiotics and antibacterial products.
