Here are two links that provide additional information on the Chernobyl Biker's site. At one point she actually had the notation on her site that "poetic license" was taken to provide this art (referring to the website itself), but that note has been taken down.
I'd suggest taking a peek at these two links:
Link 1
Link 2
and only then making up your own mind about whether her story remains legitimate in your view. It doesn't in mine.
