Abstract
The retention of a number of fission products on humus-rich peat preparations has been investigated. At a favourablepH (5–6) the following elements are firmly fixed: all rare earths; Y, Sr, Cs, Zr isotopes. They are firmly fixed by cation exchange on peat with an enrichment constant (distribution coefficient) of about 10.000∶1. Some fission products are certainly not fixed by humus, such as isotopes of iodine, Nb, not to mention the inert gases. The significance of this retention is dealt with, from the point of view of the treatment of fission product contaminated waste waters of the atomic industry and the circulation or retention of fission products carried down into the humus-rich fertile soil by atmospheric precipitation.
