Ultraviolet germicidal lamp: Is it harmful to humans?

An ultraviolet germicidal lamp is an artificial light source that emits ultraviolet C (UVC) light. It has been widely used to disinfect air, water, and surfaces in hospitals, homes, office floors, and other public places. Because ultraviolet radiation is a powerful disinfectant that kills microorganisms such as bacteria, viruses, and mold, it has been used in many sterilization projects such as indoor air purification and water treatment. But the question is, can the ultraviolet germicidal lamp be potentially harmful to human skin and eyes?

UVGI works by emitting high levels of UV radiation which effectively destroys micro-organisms on contact, the same UV radiation that has a flesh-scorching effect on humans. Once an ultraviolet germicidal lamp is switched on, it will constantly contribute to the UV radiation in the environment, resulting in high levels of exposure to people in the vicinity. This leads to over-exposure, which in extreme cases can cause adverse effects such as sunburn, DNA damage, and skin cancer.

In addition to skin damage, high doses of UV radiation can be harmful to human eyes. Ultraviolet light can damage the cornea, reducing vision and even causing blindness. Studies have also shown that UV can disrupt the fluid balance of the conjunctiva, causing chronic eye redness and irritation.

Although UVC germicidal lamps are beneficial in many ways, there are also potential risks to human health. To ensure safety during the use and operation of this equipment, people should avoid direct contact when using UVC germicidal lamps, or use UVC germicidal lamps with body sensing capabilities.

In summary, UVC germicidal lamps are very useful for the disinfection of air, water, and surfaces. To ensure safe use, people should keep away from the UVC lamp or use a UVC germicidal lamp with a sensor function. In this way, there is no fear of damage to human organs when using UVC germicidal lamps.
