Abstract :
This study investigates the environmental dose rate in the Korça district through extensive measurements conducted over three years. 25,000 measurements were performed using the Portable radiation monitoring device, Atomtex AT6101C device in various urban and rural areas. The dose rates ranged from 15 nSv/h to 210 nSv/h, averaging 54 nSv/h. Data analysis was carried out using the R programming language and GNU Octave. The initial analysis focused on summer data, followed by optimizing spatially distributed dose values using data clustering. A representative grid was then mapped in ArcGIS Pro and GNU Octave, and the Kriging method was applied to ensure complete area coverage. The distribution of values was fitted to known distributions, and the hypothesis was tested using log-likelihood and χ2 tests. The findings confirm that natural radiation levels in the Korça district are very low and pose no health risk to the population (Ministria e Shëndetësisë, 2010; UNSCEAR, 2023).
