Workshop 19' (webinar) "Challenges in applying the radiation protection system in the management of NORM and radon", online, 8 December 2022
WHY THIS TOPIC? — The International Commission on Radiological Protection system of protection is based on three fundamental principles: justification, optimisation and dose limitation; they apply to three types of situations of exposure to ionising radiations: (those that can be) planned, (in case of) emergency and existing (from sources that already exist when decisions to control them are made) along with three categories of exposures: occupational (i.e. workers), medical patients and the public (ICRP, 2007, ICRPedia).
Radon and NORM (naturally occurring radioactive materials) exposures have been categorized by ICRP as existing exposure situations (ICRP 2014; 2016; Lecomte, 2016; ICRP, 2019). However, both types of sources present specificities, making the choices about the type of exposure situation and the categories of exposure somewhat challenging and areas of confusion [Cool, 2013]. In some circumstances (for example in [Euratom, 2013]), radon and NORM are considered as planned exposure situations and exposure controlled as such. ICRP has recognized that further clarity is needed on the interpretation of exposure situations [Clément, 2021].
ICRP has insisted that the optimisation principle is a systematic process that apply irrespectively of the exposure situation: fundamentally, the exposure of the individuals should always be kept ALARA below certain dose criteria, be it called “reference level” or “dose constraint” depending on the case. Nonetheless, the protection strategy should be designed based on the characteristics of the situation and the circumstances of the exposure and a graded approach might be appropriate.
The application of the optimisation principle is the cornerstone of the activities of the European ALARA Network. Furthermore, the EAN also aims to assist ICRP in the practical implementation of its recommendations and to monitor the development of the new general recommendations [EAN, 2021], as a Special Liaison Organisation.
OBJECTIVE — The EAN would like to examine how the optimisation principle has been applied in the case of NORM and radon (at workplace or in other circumstances) and whether the choices of exposure type and exposure categories affect the practical implementation of ALARA.
A webinar will be organised to present an overview of experiences and discussed if the elements of the optimisation process could be influenced by the type of exposure situation/categories of exposure:
- Selection of the appropriate dose criteria (dose constraint, reference level);
- Dose assessment;
- Identification of the protective options and selection of the best option;
- Implementation, monitoring of exposure and iteration.

Why a Working Group?
Exposure to radon represents an important contribution to the exposure of the public and the workers to ionizing radiation. In Europe, the national regulations for the protection of workers against exposure to ionizing radiation and radon in particular have been updated with the implementation of the Council Directive 2013/59/Euratom. Compared with the former Directive, the number of workplaces potentially concerned by the regulation has increased and now include many workplaces not previously aware of radioactivity and without a radiation protection system in place. The management of radon can be challenging in practice and even for radiation protection specialists, radon might not be an easy problem to solve.
Therefore, it seems appropriate for the European ALARA Network (EAN) to engage the collection of the early feedbacks of the application of the new regulatory framework to identify why questions are raised and where difficulties are met to share it to a wider audience. This action could also be the opportunity to collect good practices to address radon and share it at the same time.
In March 2021, the Working Group ALARA for Radon at the Workplace (A-RAW) was set up. The working group developed a survey instrument to collect elements from national regulation and case studies in the management of radon. The working group actively disseminated the survey and collected feedbacks from Radiation Protection Authorities/Agencies (RPA) and National Insurance Fund. A synthesis of the collected feedbacks have been elaborated.
The objectives of the working group include sharing the results and the members are looking for the opportunities to present the result in conference and by the publication of an article.

What's new in EAN?
The EAN Working Group on ALARA Culture has achieved the elaboration of a book on the ALARA principle. Optimization of Radiological Protection - ALARA: A Practical Guidebook intends to give a clear and practical picture of what is ALARA and how to apply it – and in line with the last recommendations and standards from international organizations. ALARA: A Practical Guidebook provides an extensive description of the ALARA principle, elaborates on the specificities of ALARA for the different exposure situations and is illustrated by more than 40 examples of application in different exposure situations: nuclear installation, medical facilities, 'natural' exposure, emergency exposure situations etc. The examples are coming from the real-life.
ALARA: A Practical Guidebook is addressed to organizations and peopled involved in radiation protection and its allied fields at work or having an interest in it – engineers and technicians, experts and managers etc. The Book can also be used as training material for teachers and students in radiation protection.
With ALARA: A Practical Guidebook, the Working Group and the EAN wishes to contribute to the awareness and education in radiation protection and in all its field of application. The objective is to participate to a wider and more uniform implementation of ALARA into practice, so to ensure the efficient optimisation of the exposures and the better protection of the people.

PODIUM Dissemination workshop and EAN 19th workshop Innovative ALARA Tools
Athens, Greece, 26 and 27 – 28 November 2019
2nd announcement with preliminary programme here
registration website here
Aims and objectives of the workshops
Innovations in instrumentation, computing and information technology have provided numerous tools for improving our day-to-day lives. In the same way, new and innovative approaches to radiation protection (RP) could also be developed, in particular in the ALARA process. However, as with most new technologies, issues and challenges need to be identified and tackled. The PODIUM Project and the European ALARA Network have come together to organize a joint workshop to present PODIUM results, innovative ALARA tools and discuss broadly their use in advancing RP and ALARA.
PODIUM Workshop (26 Nov. 2019)
The main aim of the PODIUM project is the development of an online dosimetry application based on computer simulations without the use of physical dosemeters. Real movements of exposed workers captured by tracking tools have been used together with Monte Carlo simulations for the development of the application. The methodology has been applied in two crucial workplaces where improvements in dosimetry are urgently needed: neutron and interventional radiology workplaces. The availability of advanced online dosimetry applications such as these in the radiation protection field will increase awareness among workers and should improve the implementation of the ALARA principle.
During the dissemination of the project results's workshop, emphasis will be given on how exposed workers can be trained by using real-time dose results to effectively apply the ALARA principle.
EAN Workshop (27-28 Nov. 2019)
The objectives of the European ALARA Network workshop are:
- to present and review recent and emerging "innovative ALARA Tools” used in the different steps of the ALARA process: e.g. radiological characterization and evaluation of the exposure, planning and decision phases and follow-up and feedback.
- to investigate the benefits of the tools and identify potential limits in their application;
- to disseminate the knowledge on innovative ALARA Tools in support of the ALARA process;
- to investigate how innovative ALARA Tools and innovation may (re)shape the ALARA process for the next years: evolution or revolution?
A significant part of the EAN Workshop is devoted to discussions in Working Groups (each participant can participate in one Working Group). The provisional topics for discussion by the Working Groups are:
- Are there specific challenges in the ALARA process that may be solved by innovative “ALARA Tools” (under development or to be developed)?
- Are there specific issues which may limit the development and/or the use of innovative “ALARA Tools” (technical, legislative, ethical etc.)? How to deal with these issues?
- What is the role of the radiation protection professionnals (RPEs/MPEs/ RPOs, ...) with respect to these tools?
- There is currently a lot of focus on research and innovation in areas beyond that of traditional RP research, notably artificial intelligence. Does IA have the potential to shape the ALARA process in the next year?
The workshop conclusions and recommendations will summarise the main points of the presentations and the discussions held during the Working Groups.
Second announcement (with programme) of the workshops is available.
