Determination of alpha particles concentration in clay bricks samples by CR-39 detector

الملخص EN

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 60 oC 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.
