Barbara

She was making another journey through North America and came across a nuclear site, she carefully avoided stepping on anything like humans and other things, when she got there most of the employees did not panic and run away, only the new ones panicked but they calmed down after they were informed that she was not a threat, the workers allowed her to feed on the radiation because she's been there so many times and hasn't caused issues, some of the workers even interact with her (be whatever)
