From what I understand, the area around Chernobyl is brimming with life, and no, not the two headed kind.
There are multiple documentaries out there about Chernobyl and area around it. (I recommend 'Wolves of Chernobyl'. A great Doc about the resurgence of Grey Wolves around Chernobyl, and how they are flourishing under a non-human environment.
From a SR perspective, I only know of a few mentions of Chernobyl in SR lore, and they contradict each other.
One stated its still has a huge BGC due to the radiation in the area (2e)
One stated it was a confirmed nest for Shadow Spirits.. (3e)
