contamination control measures. Moreover, it might indicate that the NORM
waste has to be handled in a properly controlled manner.
3.1.3 Operational assessments:
Operational surveys are needed in order to identify NORM contamination in a
fast manner during routine operations such as previous intrusive work on a pipe
due maintenance or the clean-up of potentially contaminated equipment. It is
important and necessary that field workers know how to operate the portable
radiation instruments and are able to analyse interpret the results (OGP 2008).
3.2
Control of NORM contaminated waste
The waste contaminated with NORM needs to be handled and disposed in a
proper manner following the national and international regulations linked to the
disposal of NORM waste.
Before the final disposal of NORM waste, short-term (e.g. in the offshore
platforms) and interim storage (e.g. supply bases) is required. NORM waste
should be stored in suitable containers that comply with certain requirements.
When stored or disposed, records should be developed. These records should
include (OGP 2008):
 Waste material description (scale, sludge, scrapings, etc)
 Volume of waste material
 Mass
 NORM level (activity per unit weight) of waste material.
 Method of disposal
