The gross alpha (¦Á) and beta (¦Â) activities and trace heavy elemental concentrations have been determined in Single Super Phosphate (SSP) and Nitrogen Phosphorous Potassium (NPK) fertilizers samples used for agricultural purposes in Nigeria. Cultivated farm soil samples from two regions (north and south) in the country and samples of phosphate rocks were also analyzed for gross ¦Á and ¦Â radioactivity and elemental concentrations. The beta activity concentration in the NPK (15-15-15) fertilizers was found to vary from 2410.0 ¡À 80.0 Bq¡¤kg¨C1 to 4560 ¡À 140.0 Bq¡¤kg¨C1, between 1340.0 ¡À 70.0 Bq¡¤kg¨C1 and 1440.0 ¡À 70.0 Bq
