Underestimating the time and resource required to correctly transport NORM (Naturally Occurring Radioactive Material) or TENORM (Technologically Enhanced Naturally Occurring Radioactive Material) during decommissioning could prove to be costly, not least because it is likely to cause delays in shipping. It is clear that there are many considerations required to managing the transport of NORM and TENORM. Consultation with experts at the very early stages will be essential and could lead to significant cost saving benefits.

Active Personal Dosimetry in Industrial Radiography

The International Atomic Energy Agency’s (IAEA) Specific Safety Guide No. SSG-11 which relates to Radiation Safety in Industrial Radiography states that radiography companies must ensure that employees (Category A Workers and potentially others who enter controlled areas) are subject to regular dose assessments in order to ensure that radiation doses are kept as low as reasonably achievable and dose limits are not exceeded. It is essential that reliable dose information is collected to ensure that the exposure of workers is properly controlled. Furthermore, dose assessments will also serve to highlight bad (and good) working practices. To meet this requirement, the employer will engage an Approved Dosimetry Service (ADS) so that they may provide suitable personal dosimeters together with a formal dose record keeping service.

How to manage NORM during decommissioning

NORM (Naturally Occurring Radioactive Material) or TENORM (Technologically Enhanced Naturally Occurring Radioactive Material) is a known problem and is likely to be present on every Oil and Gas facility. Concluding that NORM will not be an issue during decommissioning because it has not presented during production or maintenance shutdowns, could lead to substantial delays and unpredicted significant costs. If there is a known history of NORM, it is likely that many more locations will be contaminated that have not previously been identified. Flushing and cleaning will not remove all contamination.
