Radiation baseline levels in Lebanon : environmental survey and public dose assessment

Abstract EN

Establishing radioactivity baseline levels for the different components of the environment in Lebanon and as consequence the detection of any accidental releases are the main goals of this research work.

The essential elements of the National Environmental Radiation Survey Program are presented.

The data obtained from the radionuclides determination in fresh and drinking water, foodstuff, marine environment samples and daily air monitoring during the years 2009 and 2010 are shown.

The yearly averaged radionuclides concentrations are within the range of the previously reported values and the recorded gamma dose rate in air are within the average worldwide values.

While the annual effective dose from the intake of radionuclides by food ingestion was calculated and it was found to be lower than worldwide average value.
