Abstract:

The Brazilian Regulation CNEN NN 3.01: “Basic Requirements for Radiation Protection and Safety of Radiation Sources”, published in April 2024, has resulted in significant changes in the concepts and structure of radiation protection, mainly in relation to the planned exposure situation and existing exposure situation for occupationally exposed workers and members of the public. These changes present challenges for oil and gas industries in the perforation and extraction of petroleum when handling NORM waste. The Radiation Protection Officer (RPO), now as co-responsible, will play a fundamental role in the understanding and practical implementation of the new requirements for those industries, because the RPO must stay up to date on evolving concepts and technologies related to nuclear and radiological safety, radiation protection, and applicable regulations. The objective of this work is to present the main aspects of the new Regulation CNEN NN 3.01/2024 regarding NORM exposure in the oil and gas industries, and the challenges that will emerge with this regulation. An important aspect that can be highlighted is that industries (e.g. oil and gas) that process materials containing naturally occurring radionuclides must carry out a radiological characterization of the installation, including exposure to radon, to assess public exposure to indoor environments and the exposure of workers, observing reference values. This critical analysis will contribute to the understanding of the new regulatory requirements related to planned exposure situation and existing exposure situation applied to NORM waste from the oil and gas industries.
