Definitions

  • the present invention relates to a radiation device configured for disinfection of objects by means of ultraviolet radiation.
  • Viruses and bacteria transmitted in stores, public rooms, hospitals and other places are costly and at times deadly. Research studies report that pathogens can survive in cases up to 3 or even 9 days. In some cases, such as that one of hospitals, the bacteria and viruses are known to significantly differ to those found elsewhere and can be resistant to treatments such as antibiotics. In stores and public rooms, there are a lot of human presence and touching of materials, whereby the transmission rate of viruses and bacteria requires substantial cleaning and in cases this cleaning does not effectively remove pathogens.
  • viruses and bacteria can lead to severe illnesses and death by infections or diseases. These are transmitted by direct and indirect human contact. For example, like many viruses COVID-19 is transmitted by the droplets and fluid when an infected person coughs or sneezes. Research on related coronaviruses shows that the viruses can live for several days on surfaces and items. Similarly, many bacteria can be transmitted through direct or indirect contact with a reservoir of infectious bacteria and they can survive outside of a host and on products and surfaces to remain contagious for extended periods of time.
