An abbreviation for kollektivnoye khozyaystvo, kolkhoz (plural kolkhozy) is Russian for “collective farm.” The first kolkhozy emerged spontaneously in the 1920s as a version of the traditional Russian peasant commune, but after Stalin’s forced collectivization campaign they became state-controlled enterprises with members serving as employees. Members were permitted to hold small plots of land and some livestock, and these highly productive private plots helped families compensate for low wages and chronic shortages of consumer goods.

The approximately 600,000 workers conscripted to the Zone to “liquidate [i.e., eliminate] the consequences” of the explosion were called liquidators. Most were soldiers and reservists, including a large number of 18- to 20-year-old draftees. Their tasks included evacuating villages; digging up and burying topsoil, forests, roads, structures, and livestock; exterminating abandoned dogs and cats; digging tunnels under the reactor; and, in the case of the unfortunate “biorobots,” removing 100 tons of highly radioactive debris from the reactor roof.
