Rooms exposed to UV light had slightly less live bacteria than the rooms exposed to sunlight; 6.1 percent of bacteria in these rooms were still viable 90 days after the start of the experiment
The authors thus recommend UV protection when driving with the windows open. In 2006, Tuchinda et al. [9] reviewed the factors affecting glass UV protective properties, such as glass type, colour, interleaves and coating. They found that clear glass allows up to 90% of VIS light and up to 72% of UV to pass through, depending on its thickness. Poly ( methyl methacrylate) ( PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others ( see Compared to other industries, PET bottles for food industries play a crucial role, as these bottles act as food contact surfaces. Hence, the use of UV light to disinfect PET bottles for food industries requires the analysis of PET bottle material, the dose of UV light, duration of exposure, the disinfection environment, and a lot more factors. It does not let light pass through it, and it appears green in color. This is due to the way in which light interacts with the opaque grass. Visible light is a combination of all of the color Windows sufficiently protect interior areas of the home from UV-B light; studies suggest that using glass as a barrier against UV-B is completely effective. UV-A rays, on the other hand, can pass through untreated windows with relative ease. UV-A rays are generally considered to be less destructive than UV-B rays. Kajhhi9.
