Abstract: Techniques for Electromagnetic Field (EMF) radiation detection is provided. In one aspect, a first signal indicative at least of an EMF radiation and a second signal indicative at least of a geographical location of a personnel may be obtained from sensors associated with a handheld device of the personnel, in real-time. These signals are filtered to obtain a first pre-processed signal and a second pre-processed 10 signal, respectively. The first pre-processed signal is analysed to detect an anomaly associated with the first signal, wherein the anomaly is indicative of a deviation in the EMF radiation from an expected value of the EMF radiation. Accordingly, one or more EMF hotspots are determined in the vicinity of the personnel based at least on the detected anomaly and the second pre-processed signal. A report including at 15 least the one or more determined EMF hotspots is generated and provided to the personnel
