Natural Radioactivity in Chips samples in Locally of Iraq


The present study was performed in nuclear and radiation laboratory at university of Kufa-faculty of science-department of physics. 14 samples of chips were collected from local Iraqi markets. Using scintillation detector (NaI(Tl)), the contents of U-238, Th-232 and K-40, in the above mentioned samples , were determined. The results showed that, the average specific activity for U-238, Th-232 and K-40 were 08.75±03.31Bq/kg,3.89±1.13 Bq/kg and 245.54±08.47 Bq/kg. The results proved that natural radioactivity were comparable with the allowed world limit and no health effect for human according to radiation contents.
