This proposed work addresses this Abstract - With the surge in global dependence on wireless need by providing a low-cost, intuitive device capable of detecting and visually indicating the presence of ambient RF radiation. The system aims to democratize RF monitoring, enabling users from various backgrounds to better understand and manage their exposure.
communication systems—including mobile telephony, Wi-Fi, Bluetooth, satellite internet, and the Internet of Things (IoT)— there has been public concerns regarding the health and environmental impacts of constant exposure to radiofrequency (RF) electromagnetic radiation. Although RF radiation is classified as non-ionizing and often considered low-risk, recent peer-reviewed studies suggest that chronic and close-range exposure to even low-intensity RF radiation can lead to cumulative thermal and non-thermal biological effects. These concerns have created a growing demand for accessible and user-friendly tools that enable individuals to monitor RF exposure in their immediate surroundings. This paper presents the design, fabrication, and empirical validation of a compact, battery-powered, and cost-effective RF radiation detection device and is tailored for public usage. Through both laboratory and real-world testing, the device demonstrated reliable detection of RF emissions from consumer-grade electronics such as mobile phones and wireless routers within a range of 10 to 25 cm, thus providing a practical solution for environments lacking advanced electromagnetic field (EMF) monitoring equipment.
2. LITERATURE SURVEY Over the years, there has been several significant studies on the adverse impact of RF radiations on human lives. A study of cognitive performance , sleeping problems in people living near telecommunication base stations has been discussed also related to the impact of power density on headaches is humans. The findings highlight symptom clusters potentially linked to RF proximity [1]. Detailed investigations on the impact of continuous exposure to extremely low-frequency electromagnetic fields on the sleep quality, stress, depression, and anxiety is done [2]. Global exposures to emerging wireless technologies from applications such as mobile phones and wireless internet may present serious public health consequences. The public exposure standards are necessary for chronic exposure to low-intensity exposures [3]. The foundational guidelines presented, provide the basis for threshold assumptions related RF exposure across health disciplines [4]. The neurological risks associated with RF emissions have been elaborately discussed, underscoring the importance of public awareness tools for RF detection[5].

1.INTRODUCTION The rapid usage of wireless communication-based technologies has changed modern life. In homes, offices, transit systems, and public spaces, RF-emitting devices such as smartphones, laptops, routers, and smart wearables function continuously, creating persistent ambient RF fields. These technologies operate across overlapping spectra, often in the 300 MHz to 300 GHz range. Although non-ionizing RF radiation does not possess the energy to ionize atoms or molecules, studies have indicated the possibility of adverse health effects due to prolonged exposure.
The mobile phone usage and the related risk for glioma is studied [6]. Studies related to exposure to mobile phone radiation potentially leading to disturbance in the metabolic activity of the cerebellum have been done [7]. A novel CMOS RF amplitude detector has been developed as a practical integrated test device, that demonstrates for on-chip testing. A full wave rectification and generation of a DC voltage proportional to RF signal amplitude is done by the detector [8].
These include increased tissue heating, oxidative stress, and other physiological responses. Organizations like WHO and IARC advocate precautionary measures in monitoring and limiting exposure, particularly in high-density or prolongedexposure scenarios. Despite these recommendations, access to affordable and practical monitoring tools remains limited. Professional RF measurement systems are costly and often require specialized training, rendering them inaccessible for
