Estonian study of Chernobyl cleanup workers
The Estonian study of Chernobyl cleanup workers evaluated the possible health consequences of working in the Chernobyl area in Estonia after the 1986 reactor accident. In 1992, the study recruited over 4,800 men who worked in the Chernobyl area between 1986 and 1991. Participants were assessed in sub-studies between 1992 and 2000 and followed via linkage until 2012. The study also recruited over 7,600 unexposed men who were followed from 2004 to 2012 through linkage to external databases.
