The high rate of transmission of the COVID-19 virus has brought various types of disinfection techniques, for instance, hydrogen peroxide vaporization, microwave generating steam, UV radiation, and dry heating, etc. to prevent the further transmission of the virus. The chemical-based techniques are predominantly used for sanitization of hands, buildings, hospitals, etc. However, these chemicals may affect the health of humans and the environment in unexplored aspects. Furthermore, the UV lamp-based radiation sanitization technique had been applied but has not gained larger acceptability owing to its limitation to penetrate different materials. Therefore, the optical properties of materials are especially important for the utilization of UV light on such disinfection applications. The germicidal or microorganism inactivation application of UV-C has only been in-use in a closed chamber, due to its harmful effect on human skin and the eye. However, it is essential to optimize UV for its use in an open environment for a larger benefit to mitigate the virus spread. In view of this, far UV-C (222 nm) based technology has emerged as a potential option for the sanitization in open areas and degradation of microorganisms present in aerosol during the working conditions. Hence, in the present review article, efforts have been made to evaluate the technical aspects of UV (under the different spectrum and wavelength ranges) and the control of COVID 19 virus spread in the atmosphere including the possibilities of the human body sanitization in working condition.
新冠病毒的高传播率带来了各种消毒技术，例如过氧化氢汽化、微波产生蒸汽、紫外线辐射和干热等，以防止病毒进一步传播。基于化学的技术主要用于手部、建筑物、医院等的消毒。然而，这些化学物质可能会在未被探索的方面影响人类健康和环境。此外，基于紫外线灯的辐射消毒技术虽已应用，但由于其穿透不同材料的局限性，尚未获得更广泛的接受度。因此，材料的光学特性对于紫外线在这种消毒应用中的利用尤为重要。由于紫外线-C对人体皮肤和眼睛有害，其杀菌或微生物灭活应用仅在封闭室内使用。然而，为了更大程度地减轻病毒传播，优化紫外线在开放环境中的使用至关重要。有鉴于此，基于远紫外线-C（222纳米）的技术已成为开放区域消毒和气溶胶中微生物降解的潜在选择。因此，在本综述文章中，我们努力评估紫外线（在不同光谱和波长范围内）的技术方面以及控制新冠病毒在大气中的传播，包括在工作条件下对人体进行消毒的可能性。
