222nm ultraviolet radiation sterilization technology plays an important role in controlling and preventing the spread of diseases

According to media reports, ACGIH, the American Association of Governmental Industrial Hygienists, has released the latest document to revise the ultraviolet (UV) hazard function and dose limits. Among them, the dose limit in the far ultraviolet band has been greatly increased. The daily radiation limit at 222nm has been raised from the original 22mJ/cm² to 160 mJ/cm² (irradiation to the cornea of the eye) and 478mJ/cm² (irradiation to the skin).

In a webinar on the prevention and management of the new coronavirus organized by the WHO Radiation and Health Department, experts in medicine, photobiology and other disciplines from Harvard University and other universities focused on explaining the disinfection application of 222 nm excimer lamp in a series of pathogens and environments, which further confirming the important role played by ultraviolet radiation sterilization technology in controlling and preventing the spread of diseases.

From the experimental data, the far uvc light 222 nm product solves the pain point problem that traditional ultraviolet rays cannot directly irradiate the human body to a certain extent. This type of product takes into account both functionality and safety, and can effectively reduce and kill up to 99.9% of bacteria and pathogens on the surface of the body，which realizes the friendly coexistence of man and machine.

Industry insiders said that the United States will significantly increase the dose limit required when using the far ultraviolet band. It would effectively expand the promotion and application of far ultraviolet products in the fields of air purification, object surface and water cleaning，which would make the application of ultraviolet sterilization have higher safety expectations.

The routine trend of the new crown epidemic has increased people's daily demand for virus disinfection. UVC LED disinfection equipment has significant advantages over traditional disinfection methods. It is expected that it will be widely used in various fields in the future, which will promote the volume of UVC LED disinfection equipment. According to Yole Development, the CAGR of UVC LED market size in 2020-2025 is 52.0%, and it is expected to reach US$2.5 billion in 2025.
