131I radionuclide is the largest of radionuclides released from a nuclear accident than other radionuclides.
It should be followed by suitable reference(s) because this statement is not a part of the result of the presented experiment. The references # 1-6 just only mentioned the quantity of the released radioiodine-131I without comparing to the other radionuclides as mentioned in the written text.
We have added suitable references in line of 17 - 18.

Human organs are critically affected by 131I is the thyroid gland [7].
Put a word “which” between “organs” and “are”.
Please consider whether it was better to use singular form or plural form. It might be better if the construction of the sentence is converted to: “The thyroid gland is the most critically human organs affected by 131I.”
Thanks for your advice. We have changed such on your advicein line of 42-43

The chemical properties of 131I are synonymous with stable iodine
Consider to change the word “ synonymous” with
“similar”.

Radioisotope production facility is located in the Pusat Penelitian Ilmu Pengetahuan dan Teknologi
(PUSPIPTEK).
If it means building #10, it is necessary to mentioned that the facility is now not operating any more. When was the presented experiment performed? Please explain the time period of the experiments clearly and how is important to make this report when the facility and the production process have been totally stopped. .
Yes, of course, it means building 10. The experiment began on December, 2013 to March, 2014.We have added such on your advicein line of 58-59. The facility stopped to isotopes operation on April 2014 to November, 2016. The facility has begun production process on November 2016 to now.

This facility produces some radioisotopes, one of which is the production of 131I was routinely produced for medical purposes in hospitals and pharmacies, both domestic and export.
Considered to modify as follow :

Is that correct to use the unit of detector efficiency as (cps/Bq/m3)? Did you mean it is the detection limit of the detector? I think the detector efficiency means the percent ratio of count rate found by the detector used to the real value of the equivalent activity of the samples to be counted, does not it?
Yes, it is correct in the cps/Bq/m3 unit. It is not the detection limit of the detector. Yes, it does.
But the detector efficiency does not have to be in the percent ratio unit. We write the detector efficiency () in the cps/Bq/m3 (direct method) or cps/Bq (indirect method) to be easy to
calculate the 131I concentration (Bq/m3) in equation 3 (indirect method) or equation 4 (direct method).

It is important to put suitable and relevant reference(s) in the narration text of Experimental Methods related to both the procedures and the mathematical formulation. It feels that the procedures are not so clearly explained, so that it is difficult to adopt the procedure, when required.
We have added suitable references in line of 180, 193, 257, 276, and 284 in narration text of Experimental Methods.

The utilization of reference(s) is lack, either in relation with scientific based discussion or with the data comparison to the data mentioned in references 1 – 6.
We have added suitable references in line of 17 - 18. 131I radionuclide is the largest of radionuclides released from a nuclear accident.
137Cs is second number radionuclide, under 131I concentration, released from a nuclear accident.

It should be remembered that the data reported and presented in a scientific paper shall have contribution either on the scientific concept or comparison data with other previously reported data.
This research of 131I measurements in stack and outdoors simultaneously is the first to be performed, and has not been done simultaneous before by other centers in BATAN, except by us of PTKMR. So the data before this research does not yet exist. This research is a part of my dissertation that cannot be explained all in this paper.
General (2)
It is also important to have a main purpose or future utilization of the data presented, so that one can imagine that the performed experiment was really important to be carried out.
We hope this research can be done with variations of 8 wind direction and range of distance from radioisotope production center to the houses every 1 km to 5 km. However, this cannot be done all, because there are problems on research costs and radioisotope production facility does not the manufacturing process of 131I from April 2014 to November 2016. This research can be continued for future research to know the overall impact of dispersion 131I from the stack to the environment.
