Analysis of the spatial distribution and comparison of the levels of radiofrequency pollution in Sri Lanka's two most populous cities
Abstract
Overview
In the twenty-first century, wireless communication tools are essential, especially during a pandemic. However, it's vital to be aware of the potential detrimental health effects due to prolonged and excessive exposure to radiofrequency (RF) waves used in these systems.
Findings
- The study assessed RF radiation in GSM900, GSM1800, UMTS, LTE2.6, and WLan2.4 frequency bands in Colombo and Kandy cities.
- 31 survey points in Kandy and 67 in Colombo were analyzed using a spectrum analyzer.
- Colombo showed higher RF radiation levels, especially in the LTE2.6 frequency band, with a maximum RF level in the GSM1800 frequency band.
- This maximum level was only 0.11% of the maximum permitted level according to ICNIRP standards.
Conclusions
RF exposure in Colombo was over 50% higher compared to Kandy. Despite being within international safety guidelines, there is a need for continued monitoring and research on the non-thermal effects of RF radiation exposure, considering the rapid expansion of wireless communication tools and infrastructures.
