Radioactivity Level of the Gamma Emitters in Ismailia Canal Environment

Abstract

The activity level of the y-emitting radionuclides was measured in the different component of Ismailia Canal (bottom sediment, biota and water) by '/-spectrometry. The average activity level of the dry samples ranged from 12 to 89 Bq/kg for the detected natural radionuclides. The annual external y-dose to the living organisms in the canal, close to the sediment beds, was found to be in the range of 1.21 ±0.24 mSv/y and does not present any significant hazards when compared with the natural y-ray background around the Ismalia Canal (IC) environment which ranges from 0.80 to 1.73 mSv/y.
