The world today has been experiencing a lot of pollution due mainly to the human activities on the surface of the earth. Such activities include among others burning of fossil fuels, industrial activities, and factory activities etc. These activities in many ways have affected the environment negatively. This paper work, measured the total amount of alpha radiation from block industries in Gwagwalada Area Council of Abuja, this was achieved by using a Gamma Scout (Model GS2 with serial number A20). Measurements were taken by placing the detector at gonad level i.e. 1 metre above the sources of radiation. Four (4) cement Block industries were located, the result obtained showed that location A (Fremo Block Industry, beside Saint Many Hospital Gwagwalada), location B (Danjuma Block Industry opposite Christ Academy Gwagwalada), location C (Bone Block Industry, Old Kutunku), location D (Geoffrey Solid Block, Jeremiah Usani Road Gwagwalada) has a dose rate of 0.000035mSv/hr, 0.000020mSv/hr, 0.000118mSv/hr and 0.00005mSv/hr respectively. The mean dose rate for all the four (4) located block industries was 0.00006mSv/hr, and the mean annual dose rate was 0.lmSv/yr, these values obtained when compared to International Commission on Radiation protection (ICRP) are within the standard limit of l.0mSv/yr, therefore workers and the environment of these block industries are not exposed to high level of radiation.
