Most solar uv b is absorbed by the ozone layer.
Germicidal uv lamp spectrum.
Ultra violet uv light is invisible to the human eye and is divided into uv a uv b and uv c.
The covid 19 circumstance is rapidly changing and also it s creating concerns to change for a great deal of us.
Uv range falls between 100 and 400 nanometers.
However can germicidal uv also deal with the unique coronavirus or covid 19.
Technically the guv spectrum is defined as uv c.
Germicidal lamps emit radiation in the uv c portion of the ultraviolet uv spectrum which includes wavelengths between 100 and 280 nanometers nm.
Ultraviolet light is part of the light spectrum landing between x rays on the low end and visible light on the high end.
Prolonged exposure causes sun burn and could result in unhealthy effects on the.
The technology of germicidal lighting is referred to as germicidal uv or guv.
Uv can be divided into different ranges with uv germicidal light said to be short wavelength.
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.
Germicidal uv lamps are extremely effective and have several major advantages.
Over the last few years germicidal uv light assisted quit the spread of various microorganisms like the flu and other superbugs.
Uvgi is used in a variety of applications such as food air and water purification.
Advantages of germicidal uv.
Uv c is found within 100 280 nm range.
What are germicidal lamps.
The uv spectrum ranges from 100 nanometers nm to 400 nm.
The lamps are used in a variety of applications where disinfection is the primary concern including air and water purification.
In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.
The longer wavelengths uv described below are not produced by germicidal uv lamps.
They are part of the complete uv spectrum produced by the sun or some specialty lamps.
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.
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.
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.
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.
On top of that bacteria and pathogens cannot become resistant to uv like they can certain antibiotics and antibacterial products.
