In Rep. Murphy’s video, he stands next to a white board that mentions UV light from the sun. High-intensity UV light can indeed kill viruses. But natural sunlight doesn’t provide the UV ...

At the same UV light intensity it takes to kill 99.9% of SARS-CoV-2 in 20 seconds, a person could be safely exposed to 222-nanometer light for up to one hour and 20 minutes.

The next time you see the UV index in the weather forecast, look more closely. You can protect yourself from too much sun.

The optical filter-less structure obtains a higher sensitivity by preventing a decrease of incident UV light intensity to the sensor. Sugawa and Kuroda had previously developed a silicon ...

An UV Sensor is used for detecting the intensity of incident ultraviolet (UV) radiation – radiation lying in the ultraviolet range, with wave lengths shorter than light but longer than Xrays. UV ...

Karl Linden advises various companies promoting the use of UV light for disinfection. He receives funding from federal agencies and industry to conduct research in his role as a professor at the ...
