THIS is what happens when matter goes faster than light speed. It’s not just some blue light. You’re watching Cherenkov Radiation take place. In water, light travels slower, and when charged particles move faster, they leave behind this cool blue echo of light. 💡 For more cool science like this, catch up on episodes of @okaytobesmart on YouTube! | PBS Digital Studios

It’s a phenomenon known as Cherenkov Radiation when electrically charged particles, such as protons or electrons, travel faster than light in a clear medium like water. | U.S. Department of Energy Office of Nuclear Energy | Facebook

The Cherenkov effect, also known as Cherenkov radiation, is the emission of light when a charged particle travels through a dielectric medium at a speed greater than the speed of light in that medium. This phenomenon is analogous to a sonic boom, where a shockwave of sound is produced when an object surpasses the speed of sound. Follow @thatisnewton ,All credits to respective creators/owners.

A demonstration of Cherenkov radiation imaging in a whole body #radiationtherapy patient at the American Association of Physicists in Medicine (AAPM) 2018 meeting. DoseOptics is hoping to file for FDA market clearance next year. This video shows radiation dose as it is delivered, based on the Cheronkov effect radiation glow emitted from the patient and picked up by highly sensative image intensifier cameras synched with the dose delivery. This patient receives two doses, one for the upper body a
