an error was identified in the caption of Figure 6. Specifically, the descriptions for the left and right images were inadvertently swapped during the final manuscript preparation.The original caption for Figure 6 was: "Figure 6. Spatial distribution map of outdoor absorbed dose rates in air interpolated using the IDW method in 1 km² (left) & 36 km² grid resolutions (right)."The corrected caption should read: "Figure 6. Spatial distribution map of outdoor absorbed dose rates in air interpolated using the IDW method in 36 km² (left) & 1 km² grid resolutions (right)." This is a purely typographical error in the caption text. The figures themselves are accurate, and this correction does not affect the data analysis, results, or any scientific conclusions of the paper. The authors apologize for any confusion this may have caused.
