Electromagnetic Wave Emission Profiles: A Study of Everyday Electronic Devices

The use of various electronic devices has become an integral part of daily life. However, there is growing concern about the potential impact of electromagnetic radiation (EMR) emitted by these devices on human health. EMR can penetrate body tissues, including the brain, and may pose negative effects if exposed for prolonged periods. This study aims to investigate and comparatively analyze the electromagnetic wave (EMW) emission from different electronic devices. This research also helps to understand the contribution of different devices towards overall electromagnetic field exposure in everyday environments. The devices used in this research include laptop, iPad, smartphone, and basic phone. Measurements were taken using an EMW detector at various distances (0 cm, 5 cm, 10 cm, and 15 cm) from the devices. This research finding shows that the longer the distance of devices from the EMW detector, the lower the intensity readings collected. Among the four devices, laptops exhibited the highest EMW readings (806.2 mW/m2), followed by iPads (95.5 mW/m2), smartphones (41.25 mW/m2) and basic phones (98.939 mW/m2) at 0 cm. These results suggest that both the type of device and its distance from the EMW detector significantly influence the level of electromagnetic radiation detected, with laptops being the most substantial source of EMW.
