Ah, that&#x27;s why the games based in the exclusion zone are named S.T.A.L.K.E.R.: [something]:

The term &quot;Stalkers&quot; was later used for the scientists and engineers who explored the interior of Chernobyl&#x27;s &quot;sarcophagus&quot; after its hasty construction in 1986. In addition, &#x27;The Zone&#x27; is also a term used to refer to the 30 kilometer Chernobyl Exclusion Zone, established after the accident.</i>
