The radioactivity analysis of gross alpha concentrations were comprehensively carried out in portable drinking sachets water samples collected from sixty different locations in Abuja province, Nigeria. Using the low background gas free proportional counter (MPC-2000B-DP model) detector, the gross alpha activity concentrations values measured in the drinking water samples ranged from (0.0025±0.0001)mBqL^-1 to (0.0969±0.0001)mBqL^-1 . The computed mean gross alpha activity concentrations and mean effective equivalent dose of alpha emitters were (0.0338±0.0001)mBqL^-1 and 0.0145mSvy^-1 respectively. The obtained results revealed that the overall average effective doses for all the measured portable drinking water samples were much below the limit value of 500mBqL^-1 and reference level of 0.1mSvy^-1 recommended by World Health Organization (WHO) and poses no significant radiological health concerns.
