Why, in the first group, the Cs-137 activity in station 1 is higher than that of station 6 even though the speed current in station 1 is higher than the one in station 6. This is in contrast with the Cs-137 activity trend in group 2 in which the higher the speed current the lower the Cs-137 activity. Please explain in the text!

According to this claim, it is difficult to predict the fate of Cs-137 in the Sayung waters due to long term physical and chemical processes. Thus, the title of the manuscript should be change. Do not use the word “the fate”.

Why the R2 for figures 2 and 3 are very low? What are the levels of confidence for these data? I am personally not confident with the data you presented in these Figures since the R2 are less than 95%. Please give explanations why the low levels of confidence occur, and what are the limitations of your experimental set up? You may need to do ANOVA or other statistical analysis to reject or accept the experimental data.

Fig. 1 is not very clear, particularly the x- and y-axes. Please reproduce it and apply bigger font size!

458 Please also include the error bars for Fig. 2 and Fig. 3 as they are experimental data Final comments and recommendations:
1. The title should be slightly changed, especially by replacing the word “fate” since
there are no data which suggest the long term fate of the Cs-137 observed in this research. The suggested title is Behavior of 137Cs Activity in the Indonesian Sayung Waters
2. The authors are suggested to find someone with excellent command of English to help them with the grammatical errors as the reviewer does not have time to correct the errors one by one.
3. There are some other issues the authors need to address as listed above.
4. I am not confident with the data presented in Figures 2 and 3 since the levels of confidence are very low (less than 95%); therefore the authors need to give explanations. Failure to give explanations may result in rejection of this manuscript being published in AIJ.
