【Abstract】 The paper takes marine organisms, i.e. mussel Mytilus crassitesta lischke, clam Arca subcrenata lischke, prawn Penaeus orientalis kishinouye, Penaeus pencillatus Alcock,as well as brown algae Laminaria Japonica Aresh, green algae Enteromorpha intestinalis Link and phytoplankton platymonas sp.as material for experiment,on the understanding that certain water temperature,concentration of radionuclides in 5 × 10-8Ci/l,make use of the method of feeding radionuclides in the laboratory experiment and determine con-centra tion factors of 60Co and 137Cs in them. Counting the eatable portion,the highest concentration factors of 60Co in them are specifically 1.4 ×103,2.4×102, 7.0, 6.8 × 10, 4×102, 2.4 × 102; the concentration factor of 137Cs in the muscle of the prawn is 2.5 × 10.The authors have determinated the distribution of 60Co in the organism of the mussel and the clam.It is also determived that the biological half-life time of 60Co exists in the mussel, the clam and the prawn and that 137Cs exists in the prawn, also.Besides absortion of 60Co and 137Cs in the above described organisms,a bait of organisms and concentratration of radionuclides in the laboratory tracer experiment and the defects of such an experiment are discussed.更多还原
