إدارة المواد المشعة طبيعية المنشأ (NORM)‎ في صناعة النفظ و الغاز

الملخص EN

NORs (Naturally Occurring Radionuclides) are present at varying concentrations in the Earth’s crust and consequently also will be present in natural concentrations in gas and oil reservoirs.

The NOR concentrations in well fluids may become enhanced due to extraction processes and subsequently form NOR enriched deposits within production facilities, thereby forming NORM (Naturally Occurring Radioactive Material).

Examples include produced water, scales, sludge and pigging debris.

Uncontrolled work activities involving NORM can lead to unwanted exposure and dispersal posing a risk to human health and the environment.

These risks – or doses stemming from the exposure to ionizing radiation emerging from NORM – can be reduced by the adoption of appropriate controls to identify if and where NORM is present.

The general principles of protection against the hazards of ionizing radiation are primarily implemented by utilizing best working practices at NORM work areas.

In this respect exposure control and adequate dosimetry are the most critical components of a health and safety programme in the protection of workers.

The protection of the environment, and subsequently the public at large, is achieved by controlled disposal of NORM-waste and the adoption of emission control.
