CHERNOBYL FALL OUT IN SALT FROM CIECHOCINEK, POLAND

The initial interest in the total inventory of the radionuclide fissio n products ejected from Chernobyl has been replaced with concern about the deposition and accumulation in the environment of those isotopes with longer half lives, mainly Cs-137 and Cs-134. We present here the slightly unusual case of collection of caesium isotopes in the salt of graduation towers used in salt production. In this case, the radiocae sium first settled down from the air to the wetted surface of the grad uation tower in Ciechocinek and then, due to crystallisation of the br ine, was deposited in the salt.
