Abstract

Modern science gave rise to the invention of various technologies and incorporated several electronics, electrical appliances, and devices into our daily lives, leaving us exposed to non-ionizing radiation (NIR). Despite a large number of studies on NIR, limited work has been done to examine its effects from home appliances in Dhaka city. Hence, this study aims to bridge that gap by measuring various Electromagnetic fields (EMF) sources from the domestic environment, focusing on magnetic fields, electric fields, and radio frequency. The study also focused on health issues and awareness among 67 households. Measurements were taken for 1009 appliances and devices. And the health outcomes were assessed through a well-structured questionnaire. The results showed that magnetic field exposure was highest near fans and iron machines, while electric field levels peaked around microwaves, multiple plugs, and refrigerators. Radio frequency exposure was dominated by Wi-Fi routers, mobile phones, and laptops. However, all the values remained well below the international safety threshold. There were some common health issues reported, which are stress, mental health problems, vision problems, cognitive issues, cancer, etc. Even though there was not much conclusive evidence, as no lab tests were done to confirm the relation between biological issues and non-ionizing radiation, it can be inferred that there are some connections between constant exposure to EMF and issues such as cancer, stress, and psychological problems. Public education, safe appliance design, further experiment, and longitudinal research are recommended.
