Measurement of 222Rn , 226Ra and 238U Concentrations In Some Fish of Karbala Governorate, Iraq

In the present work, thirteen samples for local and imported fish collected from Karbala markets to determined radon (222Rn), radium (226Ra) and uranium (238U) concentrations using Solid State Nuclear Track Detector (SSNTD) type CR-39. The results show that the concentration of these nuclides ranged between (8.163-39.746)Bq ⁄m³, (0.104-0.510) Bq⁄ Kg and (0.082-0.400)ppm with mean values 21.26 Bq ⁄m³, 0.273 Bq⁄ Kg and 0.214ppm respectively. These results shown that the concentration of above nuclide were below the permissible limits recommended by ICRP and UNSCEARs therefore it is radiologically safe for human food.
