Environmental radiation monitoring survey in Lebanon

الملخص EN

This work is part of a national environmental monitoring program.

the objective is to have an Environmental Indicator by monitoring the long-term behavior of radionuclides and to provide a baseline in the event of radiological incident.

the techniques cover the monitoring of radioactivity in land and costal areas, as well as, the collection and preparation of terrestrial samples such as soil, food, vegetables… and daily measurement of dose rates in air in different locations.

the paper provides an overview of the current situation in respect to regulatory actions and technical development of radiation protection in relation to natural occurring radionuclides measurements (NORM) in Lebanon.

dose rates in air were carried out using portable beta and gamma detectors while for the other samples gamma spectroscopy methods were used.

concentrations of uranium, thorium series and potassium were quantified and the results presented consist of one-year monitoring.
