With this in mind, if you've read Roadside Picnic it's hard not to see a reference to it in the article's closing words:
For 30 years, authors have heaved their imaginations into the Zone, trying to crack the riddle of the sarcophagus—how to make sense of Chernobyl? Their imperfect answers keep the question alive.
Ah, it's explicit in a paragraph in the intro which I had not previously noted:
The background and some terminology of the game ("The Zone", "Stalker") are borrowed from the popular science fiction novella Roadside Picnic by Boris and Arkady Strugatsky and the 1979 Andrei Tarkovsky film Stalker that was loosely based on it, as well as Stalker, the film's subsequent novelization by the original authors. The term "Stalkers" was later used for the scientists and engineers who explored the interior of Chernobyl's "sarcophagus" after its hasty construction in 1986. In addition, 'The Zone' is also a term used to refer to the 30 kilometer Chernobyl Exclusion Zone, established after the accident.
