Uv Germicidal Lamp Dangers

The lamps are used in a variety of applications where disinfection is the primary concern including air and water purification food.

Uv germicidal lamp dangers.

A quartz uv germicidal lamp is used to disinfect a train at the sviblovo station of the moscow metro transit system. Depending on the wavelength and time of exposure uv radiation may cause harm to the eyes and skin. Uva 315 nm to 400 nm uvb 280 nm to 315 nm uvc 200 nm to 280 nm and uv vacuum. 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.

For uv light products that claim to clean sanitize or disinfect cpap machines and accessories tests showed the power of the uv light and the amount of time cpap accessories were exposed to this. Germicidal lamps emit radiation in the uv c portion of the ultraviolet uv spectrum which includes wavelengths between 100 and 280 nanometers nm. Uvgi is used in a variety of applications such as food air and water purification. The uv range of the electromagnetic radiation spectrum extends from 10 nm to 400 nm.

The majority of uv c germicidal lamps are in the 250 nm range that is dangerous to humans cataracts and skin cancer and should only be used where humans aren t present. The doped quartz glass allows the 253 7nm radiation to pass through but it blocks the 185nm wavelength from escaping. Uv light and health effects. Yet nardell says the perception that uv is dangerous has persisted for.

The uv segment has different sections labeled uv a 400 to 315 nm uv b 315 to 280 nm and very high energy and destructive uv c 280 to 200 nm. Additionally since uv sanitizers employ uv c light which can be dangerous care should be taken to avoid exposure to the skin and eyes. Called ultraviolet germicidal irradiation has long. The uv spectrum is separated into four parts.

Uv light also known as ultraviolet germicidal irritation uvgi comprises a segment of the electromagnetic spectrum between 400 and 100 nm.
