Photographer's Note

This time i would like to present other kind of photo. A photo from nuclear reactor near Warsaw ( exactly Swierk town). It's not artistic shot, of course but the object is interesting in my opinion. I show it for documentary purposes, only.

There is a working nuclear core - exactly seven meters below us.
It is immersed in water. This water is used to weaken the radiation which is many, many times higher than in Hiroshima after the nuclear cataclysm in 1945year (inside the core, of course).

In this photo we are observing Cherenkov radiation.
It is spectacular phenomenon. An amazing blue glow is observed inside the core. (It is very difficult to take a photo of this phenomenon)
Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron, proton...) passes through a medium at a speed greater than the velocity of light in that medium.

Here, the speed of particles - decay products - (in water) equals about 250 000 km/s and more and the speed of light in water equals 224 000 km/s
