Seawater, biota and sediment partitioning of 137Cs in the east coast of Peninsular Malaysia

Partitioning of 137Cs between marine compartments in the east coast of Peninsular Malaysia was studied with the objectives were to quantify the level of 137Cs in seawater, biota and sediment and to assess its partition coefficient of CF and Kd. The results found the level of 137Cs were low in all type of samples and seems to be not significant. Therefore, this can be concluded that the levels of 137Cs in those samples remain in the background level and there is no new input of 137Cs into this region. Moreover, the evidence discussed in this work is reasonable to highlight the possible reasons or factors affecting the partitioning of 137Cs in seawater, sediment and its accumulation in biota as well as its CF and Kd.

This study is a part of the project “Levels, Trends and Effect of Natural and Anthropogenic Radionuclides in the Malaysian Marine Environment”, which funded by IAEA under the project “K41017—Effects of Natural and Anthropogenic Radionuclides in the Marine Environment and Their Use as Tracers for Oceanography Studies (Contract No. 22192). Inline to implement this project, the authors are thankful to all personnel and project members for the necessary help during the sampling and laboratory analysis. The authors are also thankful to IAEA for funding.
