Towards a new guidance for establishing a NORM inventory
No full textIntroduction
The identification of NORM related problems is a starting point for setting up good work and management procedures in IAEA member states. In some countries information and experiences related to NORM or the management of NORM in specific industrial sectors are not readily available. To which extend NORM related problems are present, the main issues that need resolving and the type of approach that is suitable in a country specific situation are often unclear.
Methodology
A new guidance document on ’how to build a NORM inventory’ is being developed in the framework of the IAEA Environet NORM project. While the main NORM sectors are given in Safety Report No. 49, the new guidance document aims to provide a user friendly methodology in order to enable member states to step-by-step build an inventory for these industrial sectors.
Results
The new guidance document encompasses the experience of several IAEA member states where over several decades a NORM Inventories was build. The developed guidance targets both operating industrial sites and legacy sites. The guidance provides a strategy for radiological and non-radiological data collection, sampling, and the filling of information gaps. The guidance also deals with challenges linked to the absence of resources for making a NORM inventory (for example related to the available measurement methods). Key aspects of the used methodology flow chart will be discussed via worldwide case studies from different industrial sectors (zircon and zirconia industry, phosphate industry, oil & gas industry and rare earth processing).
Conclusion
The detailed approach of the new NORM inventories guidance document is demonstrated. From the participants of the international NORM IX symposium feedback is requested to further strengthen the guidance document that aims to support comprehensive national-level policy development in order to support safeguarded, effective and inexpensive NORM, waste and residue management.

Naturally Occurring Radioactive Materials in Construction
No full textDescription
Naturally Occurring Radioactive Materials in Construction (COST Action NORM4Building) discusses the depletion of energy resources and raw materials and its huge impact not only on the building market, but also in the development of new synthetic building materials, whereby the reuse of various (waste) residue streams becomes a necessity.
It is based on the outcome of COST Action TU 1301, where scientists, regulators, and representatives from industry have come together to present new findings, sharing knowledge, experiences, and technologies to stimulate research on the reuse of residues containing enhanced concentrates of natural radionuclides (NORM) in tailor-made building materials.
Chapters address legislative issues, measurement, and assessment of building materials, physical and chemical aspects, from raw materials, to residues with enhanced concentrations of natural radionuclides (NORM), processes, building products containing NORM, and end-of-life and reuse requirements.
Key Features
Presents a holistic approach in developing new reuse pathways involving experts on different (technical, chemical, physical, ecological, economical and radiological) aspects of materials
Provides practical guidance that address questions and comments regarding the EU-BSS standards linked to the processing of NORM in building materials
Investigates realistic legislative scenarios
Primarily aimed at industry and actors linked to the industry, but also researchers
Contains a strong international network of expert authors and internal reviewers for each chapterMany special thanks go to Diana Olislagers who as grant holder manager / administration representative not only took on a large part of the coordination of this action but also the creation of this book
