Analysis of the spatial distribution and comparison of the levels of radiofrequency pollution in Sri Lanka's two most populous cities.

In the twenty-first century, wireless communication tools have become indispensable in our daily lives, particularly during a pandemic, playing a crucial role. However, it is important to recognize that prolonged and excessive exposure to radiofrequency (RF) waves, which serve as carriers for these wireless communication systems, can have detrimental health effects. The aim of this study is to assess the spatial distribution and compare the levels of RF radiation emitted by the GSM900, GSM1800, UMTS, LTE2.
