Radon Levels of Water Sources in the Southwest Coastal Region of Peninsular Malaysia

Round 1

Reviewer 1 Report

The paper is little innovative but the reported data may be of interest for the world wide data-pooling. The introduction chapter is too long and can be drastically shortened with no damage to the paper content.  

The table are to rich of data, which may be of little or no use. By way of example, table 1 reports information which are not necessary, since the information reported in Table 2 are more than enough. The paper is recommended for publication, once the revisions,  listed above, are duly carried out.

Reviewer 2 Report

The manuscript focuses on the analysis of radon measurements in water samples from the southwest coastal region of Malaysia. This is part of an on-going project to map radon in Malaysia, so it is a new interesting area.

The manuscript is well conceived and well written in adequate English language. The main output of the work is described and presented in a good form. The tables and figures, and their captions, are understandable. The abstract and conclusions hit the target and the results obtained in the work. The title is appropriate. The applied methods are adequate for the aims of the study. I require two modifications to improve the manuscript:

(1) line 38, near “earth.”, add the following reference: https://doi.org/10.1016/j.apgeochem.2021.104890

(2) table 5, please compare the present results of dose rate with some results in literature (as done for the table 4 with radon concentrations).

I recommend the manuscript to be accepted for publication after the above two modifications.
