This revised report provides guidance and general information on the management of process streams or equipment contaminated with minor concentrations of Naturally Occurring Radionuclides (NORs). Colloquially streams or installation parts contaminated
with NORs are indicated as Naturally Occurring Radioactive Material (NORM). 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. Protection against the hazards of ionizing radiation are primarily implemented by utilizing best working practices
at NORM work areas. This report acts as a road map and establishes uniform approaches on NORM management. This guidance is flexible and can accommodate regulatory variations under which individual IOGP member companies may be required to operate.
