Germicidal Uv Lamp Spectrum

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.

Germicidal uv lamp spectrum.

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. Pathogen kill rate tests show that germicidal uv products kill up to 99 9 of bacteria and viruses when used correctly. Technically the guv spectrum is defined as uv c.

Uv b a small but dangerous part of sunlight. Uv can be divided into different ranges with uv germicidal light said to be short wavelength. They are part of the complete uv spectrum produced by the sun or some specialty lamps. On top of that bacteria and pathogens cannot become resistant to uv like they can certain antibiotics and antibacterial products.

Ultra violet uv light is invisible to the human eye and is divided into uv a uv b and uv c. Advantages of germicidal uv. The covid 19 circumstance is rapidly changing and also it s creating concerns to change for a great deal of us. In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.

Uvgi is used in a variety of applications such as food air and water purification. Most solar uv b is absorbed by the ozone layer. The longer wavelengths uv described below are not produced by germicidal uv lamps. Over the last few years germicidal uv light assisted quit the spread of various microorganisms like the flu and other superbugs.

Prolonged exposure causes sun burn and could result in unhealthy effects on the. 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. Germicidal uv lamps are extremely effective and have several major advantages. Uv c is found within 100 280 nm range.

The technology of germicidal lighting is referred to as germicidal uv or guv. 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. Safety tips for using germicidal lamps. The uv spectrum ranges from 100 nanometers nm to 400 nm.

Uv range falls between 100 and 400 nanometers. 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 lamps emit radiation in the uv c portion of the ultraviolet uv spectrum which includes wavelengths between 100 and 280 nanometers nm. What are germicidal lamps.
