The aim of this work is to investigate radiation dose around some GSM base stations within Ota and Lagos metropolis in Nigeria. This was done using a radiation alert monitor (M4EC) manufactured by S.E. International, Inc., USA. The measurements were carried out on ten different masts cited in some places in Ota Ogun State and Lagos. Measurements were carried out by positioning the radiation meter at five various distances to the masts and the mean value considered. The study showed that there is presence of radiation levels from masts beyond the background radiation levels but is within the permissible limit for public. The radiation dose measured where one mast was erected varied between 0.001 and 0.027 x 10-3 mSv/week. The radiation measured from location where two masts were erected varied between 0.001 and 0.039 x 10-3 mSv/week. The radiation measured where three masts were erected vaied between 0.001 and 0.050 x 10-3 mSv/week. The highest equivalent dose was obtained at 1 m away from the masts where three masts are erected and the radiation went to minimum at 16 m away from the masts. Also, where one mast was erected the highest radiation was measured at 1 m and went to minimum at 6m away from the mast except for BS 3 with the shortest mast 84 ft where minimum radiation was obtained at 8 m from the mast. It can be concluded that radiation dose depends on the number of mast erected in a particular location which implies that the more the number of masts in a location the more the distance should be kept from them. The study showed that the height of the mast plays significant roles in the radiation incurred by people around, in other words, the higher the mast, the safer it is for those around it. Technicians should be advised to desist from crowding a location with too many masts since the higher the number of masts the higher the radiation incurred the mast should be of appropriate height.
