Those images are breathtaking but idk about the rads lol. I did some interesting in - depth work about Chernobyl for a research project, and The "containment" around reactor 4 is in pretty awful shape.
On a second note, I have toyed with the notion of in game barter systems in many sceneries I have run, I that is a concept that adds a great deal of fun (IMO) some people dislike it.
Doing a dea/gang/cartel with tradable goods and players needing to scrounge up ammo to survive was one of the better ones that I ever found that actually worked.
