This paper presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation within University of Uyo campus, Use Offot, Uyo, Niger Delta region of Nigeria. Mean annual outdoor and indoor equivalent doses of 0.284mSv/yr. and 0.854mSv/yr. respectively were recorded, being less than 1mSv/yr. maximum recommended limit for general public. Mean annual outdoor and indoor effective doses of 0.174mSv/yr. and 0.645mSv/yr. respectively with a total of 0.819mSv/yr. were computed. The mean outdoor and indoor ELCR values of 0.61x10-3 and 2.26 x 10-3 respectively, with a mean total of 2.87 x 10-3 were also computed. The results though higher than the world’s average, are comparable with those of some other locations within the Niger Delta region.
