Detection of NORM contamination in LNG systems
Abstract: Naturally occurring radioactive material (NORM), which is present in the oil and gas industry, can pose a risk to the workers engaged in the activities in this field. Nevertheless, to our knowledge, there is no study on NORM presence and NORM measurement in liquefied natural gas (LNG) fuel systems and installations. Therefore, the question on whether NORM, particularly radon and radon progeny, can pose a risk to the health of employees, is still open. This study provides the initial base for further investigation and real NORM measurement. In this study, all stages of radon and radon decay products movement and deposition starting from natural gas production till the final destination are analyzed and reviewed. Several techniques for NORM detection and measurement are proposed. In the case if radon levels exceed the reference level, several actions towards radon reduction are proposed.
