A connection between non-ionizing EMF and human health has been stipulated by an increasing number of studies and symptoms characterized as Electro-hyper-sensitivity (EHS) are frequently reported. When a building is exposed to such kind of EMF radiations it can be referred as a sick building. This research aims to identify and measure EMF hot spots and vulnerable buildings in Addis Ababa. Data for the intensity of the EMF radiation was taken using HF 59B analyzer for higher frequency and 3951A M/E analyzer for Electric field and magnetic field around EMF sources, and ArcMap 10.3 GIS is used to model and analyze the data, the analyzed result has shown that, from the total area which is 54000ha of Addis Ababa 31.25% (16235ha) of the land is in hot radiation zone which is designated as extreme exposure; 30.5%(15843ha) of the area is severely exposed; 21%(10906ha) of the area is slightly exposed and the remaining 17% (8967.99ha) of the area have a negligible amount of exposure. Buildings with in these hot EMF radiation zones have to use measures to decrease the intensity of radiation and keep the user safe and healthy.
