 un (University of Ilorin)\nAssessment of activity concentrations of 40K\, 
 238U\, 232Th and gamma dose rate (DR) was carried out over a latrite minin
 g field using a well calibrated Super-Spec (RS-125) gamma spectrometer\, a
 long Ajese-Ipko road\, Ilorin-south\,  Kwara state\, Nigeria. The results 
 of the radioactivity measurements were used to assess the radiological haz
 ards associated with the latrite mining field and it’s suitability as bu
 ilding material. Fifty (50) measurements of the activity concentration of 
 the radionuclides were obtained at about 1 meter above the topsoil to cove
 r a large area. For each of these 50 sample points\, measurements were tak
 en four (4) times for better accuracy. The mean activity concentrations of
  238U and 232Th are higher than their corresponding global average of 32.0
 0 Bqkg-1 and 30.00 Bqkg-1 respectively provided by UNSCEAR. This is a caus
 e for worry as significant enhancement in the concentration of 238U and 23
 2Th will increase the level of the background radiation and possibly rende
 r the soil unfit for use in building and construction purposes.  The resul
 ts of the radiological impact parameters (RIP) such as the mean values of 
 the indoor radiation dose rate (Din). indoor Annual Effective Dose (EADind
 oor) and Annual Gonadal Equivalent Dose (AGED) are above the recommended l
 imits provided by UNSCEAR. Since other hazard parameters are close or coul
 d possibly be approximated to the permissible limit\, this implies that th
 e lateritic soil from this mine field may not be too suitable for building
  and construction purposes (either as raw material or finished product).\n
