| Abstract: | The paper presents the first part of a research work on transfer of radioactive nuclides from sea water to sediments and marine organisms. 137Cs, 184Cs,65Zn,60Co, 59Fe, 54Mn were added to sea water in an aquarium of 1.2 ton, in which the sediments were laid on the bottom. The concentration factors of these nuclides in suspension and sediments were determined, respectively, by means of super-filtering and S-80 multi-analyser with Ge (Li) gamma-ray detector. It was found that the concentration factors of 137Cs and 134Cs were less than those of 65Zn,60Co, and 54Mn in the suspension for two to three orders; 59Fe in filtered sea water was not detectable. It was shown that after nuclides entering sea water, 137Cs and 134Cs were mainly in ionic state, and 65Zn, 60Co, 59Fe and 54Mn in particle or colloidal state. The concentration factors (96 h) of these nuclides in sediments were less than that in suspension also for two to five orders. Thus, a conclusion may be that adsorption rate of nuclides by sediments is slower. |
