Control of the concentration of Radon in the air of the underground tunnels of Sidra Ltd. (applied research: step one)

Radon (Rn) is a colourless, odourless and flavourless gas that, in closed environments, can reach high concentrations. Sometimes, it’s descending radioactive isotopes release high radioactive particles during decay, which own such penetration powers to be able to sometimes damage the bronchial epithelium of people breathing in the air when there is a high Rn concentration. This paper concerns the technical-scientific procedures used to achieve the reduction of Rn concentrations in the tunnels of Sidra Ltd., to create safe working conditions for the operators inside these tunnels.
