GSM Base Station Radiation Level: A Case Study Of University Of Nigeria Environment

摘要

Abstract :- Electromagnetic radiations at high frequencies have varied effects on different biological media. Investigations are on going to ascertain the effects of electromagnetic radiations on human, especially with the proliferation of communication masts in the cities. In this paper, efforts are geared towards the assessment of the level of impact on the environment especially as it concerns the pulsed signal at microwave frequencies. This paper will also offer some perspectives on the potential implications for human health exposure on the radiation should the exposure limit exceed the recommended safety zone of about 300 metres away from the base stations. Two measurement procedures were implemented here; one for determining the power density due to the base station of interest, the other for evaluating the total exposure within the university environment. The maximum level recorded at the various sites was 1.3 mW/m2 while the total sum of radiation level encountered was about 2 mW/m2. The investigated level was compared with the international safety level and was found to be below the recommended safety level as provided by international agencies such as ICNIRP and ANSI as examples.
