    | The Pripyat River (Ukrainian:
      Прип’ять,
      Pryp”yat’; Belarusian:
      Прыпяць,
      Prypyac’; Polish:
      Prypeć) is a river in Eastern
      Europe, of approximately 710 km (441 mi.) length. It flows east
      through Ukraine,
      Belarus,
      and Ukraine again, draining into the Dnieper.
       The Pripyat passes through the thirty-kilometer zone around the Chernobyl
      reactor, where the nuclear
      disaster happened. Therefore it transported and still transports radionuclides
      downstream. The concentration of caesium-137
      is still increasing in dredges and has not been reduced in the river
      sediments.
