Professional opinion

Dr. Eli Stern

Objectives

To quantitatively analyze all radiological risks of the potential operation of a new phosphate mine at the Sde Barir site to residents of Arad and Kassaifa , located approximately 4 km from Arad and 3.5 km from Kassaifa. The assessment included a quantitative analysis of exposure to airborne dust drifting towards the towns that contains concentrations of radioactive elements from the uranium chain (including radon exposure), while focusing on and differentiating between dust that is constantly being emitted from mine operations and dust that is emitted from rock blasting which takes place at the mine at slightly less than 200 per year. The assessments include calculations of various types of dissipation that cover both the continuous emission of dust (and radon) from the mine and clusters of one-time emissions caused by the blasts. Finally, the doses to which people might potentially be exposed are assessed and compared to international and Israeli standard threshold values. 

In addition, the report includes recommendations of numerous and detailed measurements to be carried out during a "trial year of mining".

Implications / Applications

A significant tool to facilitate decision-making on the issue of permits to operate mines (used by district committees).
