Abstract
This study aims to assess the committed effective dose due to the intake of Po-210 from the consumption of fish in Arabian Gulf countries. Twenty different kinds of fish, which represent the most common fish species consumed in the Arabian Gulf countries, were analyzed using alpha spectrometer technique. Po-210 activity concentrations in fish samples were found to vary over a wide range from 0.1 to 14.7 Bq kg(-1) fresh weight. This variation of Po-210 concentrations between various type of fish samples might be attributed to the feeding type pattern and the size of fish. The annual committed effective dose due to ingestion of Po-210 in fish species for adults in the Arabian Gulf countries was estimated and found to vary from 38 mu Sv in Bahrain to 85 mu Sv in Oman with an average value of 59 mu Sv. These values are considered relatively high compared to those reported in some other regions. However, it is still much lower than the world average ingestion dose due to natural radiation sources.
