Um, Chernobyl is still extremely radioactive. You probably mean the exclusion zone which is really not that bad, there’s even tourists going there. But it’s still not recommended to live there due to cumulative exposure.
So the site itself is still deadly, but the areas around it are not? Would that be the case for a nuclear attack as well? Like ground zero would stay deadly but the rest of the city would be safe a few decades later? I just realized that I don’t actually know very much about nuclear fallout. How are Hiroshima and Nagasaki safe?
The clouds of radioactive gases carry radiated dust particles that are carried by winds and settle on the ground, roofs, etc (fallout). That’s why after Chernobyl or the Japanese cities were attacked it was very important which way the wind was pushing the clouds carrying the tiny debris, ash, and dust and how the Chernobyl disaster was detected by other countries in the path.
You probably also want to avoid trying to grow any crops in the area because one way to deal with the radioactive dust is to bury it under the top soil, and buildings that have been closed since Chernobyl that still have the dust trapped inside are still very dangerous.
Edit: the bombs in Japan exploded high above the ground to maximize damage and minimize fallout. The gases were carrying less radiated particles, and mostly dispersed after the initial blast or carried by winds. The gases over Chernobyl kept going until the fires were out.
It’s been a couple of decades since I watched the documentary so maybe my memory is betraying me but from what I remember the bombs dropped on Japan didn’t touch the ground. They detonated in the air so there technically isn’t a ground zero.
Generally the really nasty gamma emitting fission products lose their nastiness after a couple of months. Their half lives tend to be counted in hours.
They overturned the dirt in the exclusion zone to bury the fallout so that it’s less of a possibility for it to move around. You wouldn’t want to live there, drink from the groundwater, farm there, etc.
I was gonna answer that most animals don’t live as long and reproduce faster than humans (so populations survive despite increased cancer risk), but when I looked into it I found a deep rabbit hole.
In the case of wolves, I’m sure plenty died early on, because the populations present appear to have some genetic immune adaptations that protect them from cancer.
I know other species (like frogs) have dark skin because the melenin increased the survival rate of the darker frogs at the time of the accident.
So that is to say probably a lot of wildlife died, and that natural selection lead to some critters that are pretty resistant to radiation.
I think we can safely say with hindsight, it was very safe. Reactor 4 was caused by a fluke of circumstances and a few mistakes. It was otherwise a very safe reactor. Once they understood the failure they are able to adjust protocol to ensure it doesn’t happen again. It made the other reactors even safer.
The same thing happened with three mile island. Unit 1 safely continued operation until 2019, which only stopped because of financial pressures (competition with Methane), not because anything was wrong.
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.
The wildlife is just left alone, I wouldn’t call it safe from radiation, they still have a higher incidence of mutations than animals outside the contaminated zones. It’s just that some radiation and no humans, happens to be better for wildlife than no radiation and lots of humans.
How is Chernobyl safe for wildlife now, but this book is still dangerous?

Complex topic. It would depend on the bomb in question. Some are more “dirty” than others.

Interesting video on Chernobyl and the people still living in the exclusion zone.
https://www.bbc.com/travel/article/20140116-cooking-in-the-danger-zone-chernobyl
I can’t watch the video via the BBC site but it exists elsewhere.
Thanks!
they didn’t say the book is dangerous, they said it’s radioactive
It isn’t “safe” it’s “safe enough” for limited visits to the exclusion zone and VERY limited visits to the sarcophagus that enclosed the old reactor
So what about the animals around there? Are they all dying from radiation poisoning, or turning into Godzilla, or something?

Wow, that’s actually really cool! Not the dying part, but the adapting part. Thanks for sharing!
Chernobyl was made into a TV show while this book appears to be just a book.
So if we make a movie about this book then it can be handled again? Or does it have to be a full 10 hour show?
fun fact: the other three reactors in Chernobyl were put in operation again AFTER reactor 4 blew up
I believe the last one for 14 additional years
how safe that was is another question though

I mean, RBMK based reactors are still in use today, no?
Different radioactive materials have different half-life periods.
