Time-Dependent Study of Electromagnetic Field and Indoor Meteorological Parameters in Individual Working Environment

摘要

Human beings in modern society are facing wide-range of electromagnetic (EMF) radiations from few hertz (Hz) to gigahertz (GHz) range. Its minor sources are power supply, personal computers, Wi-Fi routers, Zig-bee, cell phones and base trans-receiverstations (BTS) devices. We have extensively used them in microenvironments like offices, restaurants, buses, close auditorium, etc. In such indoor environments, the air quality incorporates various gaseous emissions, temperature, humidity, particulate matters, etc. Accordingly, the cumulative effect of EMF and air-quality parameters can change human health and quality of life. This paper described exposure assessment of EMF and indoor meteorological parameters in the individual microenvironment during working and non-working hours. The results were obtained via broadband methodology for assessment of EMR and point source methodology for temperature, relative humidity and particulate matter (PM). The kriging model in surfer software approved to be moresuitable to show accurate gridding of EMF during working and non-working hours. No significant change observed in time-dependent analysis of EMF, temperature, humidity and PM count. However, telephony band was dominant during whole analysis. Hence, moreinvestigations are required to identify the quantitative relation between these independent parameters.
