Since this year, experts in the fields of virology, immunology, aerosols, architecture, and physics have studied methods that may prevent the spread of new coronaviruses in indoor spaces. Based on the research results, scientists recommend using UVC lamps indoors as an easy-to-develop and affordable method to suppress the spread of the virus. Scientists from the Institute of Photonic Sciences in Spain, the University of the Basque Country, the Technology/Israel Institute of Technology and the University of Southampton in the United Kingdom have reportedly discussed existing UVC light sources, such as fluorescent lamps, microcavity plasmas, LEDs, and others Alternatives and unconventional ways to produce UVC light. Scientists believe that by applying these UVC lights to the ventilation system of buildings and unused public indoor places, it is possible to quickly and effectively inactivate airborne and new crown viruses deposited on the surface. In addition, scientists also investigate the cost of deploying UVC technology globally. The conclusion is: investing billions of dollars in the world for the development of UVC light sources can protect the health of about 1 billion people worldwide. In indoor public places such as offices and schools, in addition to airborne viruses, viruses can also be transmitted on frequently contacted surface areas such as elevator buttons, door handles, and handrails. Therefore, scientists say that UVC light can reduce the spread of viruses and can meet the rapid, large-scale and low-cost deployment needs. At present, its implementation problems are only limited by the existing production capacity. This research has recently been published in the journal “ACS Nano”.
