Biomedical engineers from Dartmouth College (USA) were able to prove the real existence of a mysterious glow in the eyes, which has been repeatedly complained about by patients undergoing radiation therapy. With the help of the new CDose camera, scientists were able to record this glow for the first time, having received documentary confirmation. It turned out that we are talking about the famous "Cherenkov radiation" generated by charged particles.
To a wide audience, Cherenkov radiation is best known for the ghostly, cold blue flicker of nuclear reactors in the coolant. It occurs when a charged particle moves through a dielectric medium faster than the limit of the speed of light in this medium allows. During radiotherapy, the human body is also exposed to radiation, and under certain conditions, the passage of particles through the vitreous body (the transparent contents of the eyeball - ed. Tekkult) just generates such a glow.

It is extremely difficult to detect this glow, it is short-lived, dim and occurs irregularly. The eye is not a light bulb that can glow continuously. The patients themselves see these flashes only because they occur in the immediate vicinity of the photoreceptors, and with the eyelids closed, just inside the eye. It is not surprising that for a long time it was virtually impossible to fix the mysterious phenomenon.
The discovery is extremely interesting because Cherenkov radiation is not just a glow, but a complex multifaceted effect that is used in physics to analyze the behavior and characteristics of particles. And now, knowing the nature of "light from the eyes", one can find patterns and better study the effect of radiation therapy on the human body. And at the same time, study radioactive particles in general, because the glow energy is far from symbolic and can pose a threat or, conversely, be useful.
