Project: Radioactivity – NORM contamination of LNG fuel systems

In this project, we study if liquefied natural gas (LNG) fuel systems are contaminated by natural occurring radioactive material (NORM). The general questions are how to detect contamination and what measurement techniques should be used to produce trustworthy results.

More about the project

The global consumption of liquefied natural gas (LNG) tends to increase further. One of the reasons is its less polluting nature compared to heavy fuel oil (HFO) and diesel oil (DO), which currently are the major fossil fuels. Therefore, many countries switch to LNG fuel and Sweden is no exception. However, there is a risk that the operation and maintenance labour is exposed to contamination by natural occurring radioactive material (NORM).

In this project, we study if LNG fuel systems are contaminated by natural occurring radioactive material. The general questions are:

  • How should one proceed to detect NORM contamination in LNG fuel systems (marine and land based)?
  • What measurement techniques should be used to produce trustworthy results?

We are also interested in an increased understanding of which fuel system components and/or locations that have an elevated probability of NORM contamination due to accumulation over time.

The project is part of the research in the Welding Mechanics Laboratory research group.
