The aim of the present work is to determine the alpha particles concentration in clay bricks samples
taken from Hilla, Karbala, Najaf, Baghdad, Diyala, and Samarra governorates, emitted from the
radioactive elements (radionuclides) (U-238, Th-232, Ra-226, and Po-218) by using nuclear track
detector (CR-39), taken from many places of Iraq. Used one month irradiation time and then etched by
6.25 N of NaOH solution at temperature of 60oC for 6 h.
The results obtained have shown that the highest average alpha particles concentration in clay
bricks samples was found in Najaf region which was 4.65 ppm, while the lowest average alpha
particles concentration was found in Diyala region which was 1.26 ppm.
