Abstract :
The rapid industrialisation of Sahelian economies exposes a growing population of workers and residents to physical, chemical and radiological risks that remain poorly documented. This article proposes an integrated methodological framework for assessing and monitoring these risks, built around the assess-prevent-monitor-improve loop and a set of six quantitative indicators linking occupational safety and epidemiology. The framework is applied to naturally occurring radioactive material (NORM) in extractive industries and to indoor radon, using case studies calibrated on Chadian practice: southern oil fields, a cement plant and a fifteen-building radon survey. Results show that simple measurement tools, a shared risk-rating grid and a strictly applied hierarchy of prevention can bring exposures below international reference levels at costs compatible with the budgets of companies in the subregion. A minimal ten-line dashboard for occupational health services in developing countries is proposed.
