Alpha activity in 20 soil samples of the University of Kerbala (Agricultural College) was determined using CN-85 detector. Results showed that radon concentrations varied from 1020.375±3.54 to 7596.125±9.68 Bq/m3
with an average of 4308.25±7.17 Bq/m3. AED varied from 0.825±0.10 to 6.142±0.27 mSv/y with an average of 3.48±0.203 mSv/y. Radium content in Bq/kg varied from 0.025±0.01 to 0.188±0.04 with an average of 0.1064±0.035. The results of EM and ES varied from 0.19±0.04 to 1.42±0.13 mBq/kg/h with an average of 0.80±0.0981 mBq/kg/h and from 8.93±0.33 to 66.53±0.90 mBq/m2/h with an average of 35.70±0.67 mBq/m2/h, respectively. However, uranium activity in unit’s ppm and Bq/kg varied from 0.06±0.02 to 0.45±0.07 with an average of 0.25±0.055 and from 0.74±0.09 to 3.15±0.18 with an average of 3.15±0.18, respectively. Thus, the results of this study were less than the world average, which would not pose a significant risk to human beings.
