DESCRIPTION:Speakers: Mojisola Usikalu ()\nSoil samples in the agricultura
 l farmland surrounding selected quarry sites in Ondo and Ekiti states was 
 assessed to measure the concentration of 238U\, 232Th\, 40K using NaI (TI)
  detector and estimating radiological parameters in order to determine the
  possible radiation effects to the farmers and member of the public consum
 ing the farm products. Analysis of the result revealed that the average co
 ntents of the measured radioelements were 15.19\, 31.92 and 1354.15\, 16.5
 5\, 38.60 and 1185.44\, 24.66\, 34.25\, 1385.89 and 18.10\, 37.66\, 1242.6
 7 Bq/kg for Iyin\, Ita ogbolu\, Aaye and Ikere quarry sites\, accordingly.
  The absorbed dose rate in the soil samples ranges from 64.91 nGy/h in Iyi
 n quarry site to 146.88 nGy/h in Aaye quarry site with the mean value of 8
 6.06 nGy/h for the four study locations. The concentration of 40K\, the ab
 sorbed dose rate\, the indoor and outdoor annual effective dose and the ex
 cess lifetime cancer risk were higher than the world limit in the study ar
 ea\, predisposing the member of the public in these locations to hazard of
  radiation exposure. There is the need for constant monitoring of the quar
 ry sites\, provision of radiation protective shield for workers mining at 
 the sites\, awareness of radiation risks to the farmers and members of the
  public around the quarry sites.\n\nhttps://indico.tlabs.ac.za/event/139/c
