ABSTRACT
This study was undertaken to determine the natural raaionuclides activities of 238U, 232Th, and 4°K
as contaminants and their distribution from dust particles obtained from selected qua1Ties in Ekiti
and Ondo States. This work was performed in four quarries sites located in Ekiti and Ondo States
and a control sample. The radioactivity concentrations of the natural radionuclides (238U. 232Th and
4°K) in the collected quarries dust samples were determined by gamma ray spectrometry. The
radioactivity concentration values in the investigated dust samples ranged from (8.02 ± 2.0 to 25.00
± 4.0) Bq kg-1 for 238U, (10.02 ± 1.0 to 32.06 ± 2.0) Bq kg-1 for 232Th, and (600.06 ± 2.0 to
1014.06 ± 1.0) Bq kg-1 for 4°K. The total absorbed dose rate ranged from 34.944 nGyh· 1 to 73.051
nGyh·' with the control sample with the lowest absorbed dose rate and EKT 1 with the highest
absorbed dose rate. The total absorbed dose rate values increase with the activity concentration. and
consequently enhances the radiological impact on the people living in the surrounding communities of the quarries .
