| 中文摘要: |
| The transfer of 137Cs, 60Co along Platymonas sp., Brachionus plieatilis Müller and Tilapia mossambica Peters was studied by using the tracer methods of both 137Cs and 60Co with Ge (Li) Gamma ray detector and S-80 type multichannel-analyser for measuring the radioactivity of the sample. The experiment was carried out in four groups and the period of the experiment was fifteen days. It was found that 60Co could be transferred along seawater→Platymonas→Brackionus→Tilapia, and that 137Cs could only be transferred from seawater to Platymonas. 137Cs was not accumulated by Brachionus in any group of the experiment. Brachionus ingested 60Co mainly from Platymonas, when 60Co was ingested by Tilapia; Brachionus played an important role in the transfer and the Tilapia ingested 137Cs mainly from seawater. |
