Advantages of germicidal uv.
Germicidal uv lamp spectrum.
Ultraviolet light is part of the light spectrum landing between x rays on the low end and visible light on the high end.
Germicidal uv lamps are extremely effective and have several major advantages.
Uv can be divided into different ranges with uv germicidal light said to be short wavelength.
Technically the guv spectrum is defined as uv c.
Uv c is found within 100 280 nm range.
Uv b a small but dangerous part of sunlight.
Ultra violet uv light is invisible to the human eye and is divided into uv a uv b and uv c.
On top of that bacteria and pathogens cannot become resistant to uv like they can certain antibiotics and antibacterial products.
The technology of germicidal lighting is referred to as germicidal uv or guv.
Most solar uv b is absorbed by the ozone layer.
Pathogen kill rate tests show that germicidal uv products kill up to 99 9 of bacteria and viruses when used correctly.
Uvgi is used in a variety of applications such as food air and water purification.
What are germicidal lamps.
Approximately 95 of the ultraviolet energy emitted from ster l ray germicidal lamps is at 254 nanometers the region of germicidal effectiveness most destructive to bacteria mold and virus.
The lamps are used in a variety of applications where disinfection is the primary concern including air and water purification.
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.
In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.
Germicidal lamps emit radiation in the uv c portion of the ultraviolet uv spectrum which includes wavelengths between 100 and 280 nanometers nm.
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.
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.
Uv range falls between 100 and 400 nanometers.
The longer wavelengths uv described below are not produced by germicidal uv lamps.
Philips low pressure uv c lamps have their main emission at 254 nm where the action on dna is 85 of the peak.
Safety tips for using germicidal 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.
Prolonged exposure causes sun burn and could result in unhealthy effects on the.
Over the last few years germicidal uv light assisted quit the spread of various microorganisms like the flu and other superbugs.
