Abstract
Introduction: The increase of mobile phone usage and demands has increased the installation of the mobile base station as the cellular phones' network carrier. Even though there is growing concern about the health risks that may be caused by living nearby a mobile base station. The effect of radiofrequency (RF) radiation emission from this mobile base station is still highly uncertain and controversial. Objective: The purposes of this study is to examine the effect of (RF) radiation from mobile base station to school children by investigating the micronuclei (MN) frequencies counts in buccal mucosa cells and its potential health effects among primary school children in Selangor. Method: Stratified random sampling were used to gather a total of 201 primary school children which were then grouped into exposed and non-exposed groups based on the existence of mobile base station found in their school territory. In this context, exposed group are school children whose school located in the vicinity of mobile base station ( <200 metres) and non-exposed group were among school children whose school located distant from the mobile base station (>200 metres). RF measurements were measured at each 10m intervals starting from the school to 200m by using the Digital RF Analyzer (Model HF35C). A set of questionnaires were also used to examine the socio-demographical background, other sources of non-ionizing radiation and self-reported health effects among school children. The buccal mucosa cells from the oral cavity were sampled to evaluate the micronuclei frequencies by using Micronuclei Assay. Result: The RF values shows different RF pattern among both exposed and non-exposed school when sampling during weekend and schooling days. Overall, the non-exposed group has a higher median (11.50) of MN frequency count as compared to the exposed group (6.50). There is no significant association between MN frequency and RF level with relatively weak association (r=0.097) reported. The socio-demographic backgrounds, household sources of non-ionizing radiations and their residential settings shows no significant association with micronuclei frequency, however, a significant association between hair loss problems with micronuclei frequency were found in this study. Conclusion: The fluctuations of RF levels depend on its fixed point of installation, and the surrounding environmental settings. Single source of RF from mobile base station is insufficient to conclude the potential DNA damage in this context, in fact, other sources of non-ionizing radiations and contributing factors that might affect the MN frequency shall be taken into consideration to better estimation of the potential health effects in the future. Keywords: mobile base station, radiofrequency radiation, micronuclei, children
