…I was gonna say it took until it was shrunk down to the thumbnail to see red, but nope, it actually has red in it in the thumbnail.
Guess this is specific to how often you see cans of coca-cola?
Here, I put the image through a ditherer (only available colours are black, cyan, white). I don’t see any red at all now.
[edit}
Actually, that “red” is mostly just gray so I played myself here. Still, the luminosity must be closer to red before I detect it as red, white doesn’t do it.
Chernobyl isn’t safe safe, it’s just safe enough for wildlife to survive there, possibly with lowered life span and quality of life.
Also, there’s a decent danger of radioactive dust coming off the book if it’s handled. It may not be that radioactive, but if it clings to you, or you breathe it in, it will do considerably more damage than if it was all one solid rock that made geiger counters click.
