This study presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation around radiological sections in Federal Teaching Hospital Gombe, Gombe State, Nigeria using a well calibrated Rados-200 meters and a Global Positioning System (Garmin 765). The mean annual outdoor equivalent dose of 0.078 mSv/y. was measured. Mean annual outdoor effective doses of 0.1358 mSv/y. and 0.0950 mSv/y. were computed respectively, that were less than 1 mSv/y. maximum recommended limit for general public. The mean outdoor ELCR values of 0.3330 x10-3 was also estimated. The results though below the world’s average, are comparable with those of some other locations similar to the study area.
