However, this effect has diminished sharply over time. Soviet authorities started evacuating people from the area around Chernobyl only on the second day after the disaster (after about 36 hours). By May 1986, about a month later, all those living within a radius of the plant (about 116,000 people) had been relocated. This area is often referred to as the zone of alienation.
