and safety of workers exposed to ionizing radiation worldwide.
One of the challenges in implementing the harmonized methods outlined in ISO 24426 is the potential loss of some already collected data. As existing datasets from ESOREX and UNSCEAR are based on different methods, transitioning to a unified standard might render portions of this historical data incompatible or unusable. This could lead to gaps in longitudinal studies and complicate efforts to track long-term trends in radiation exposure. Addressing this issue requires careful planning to integrate and preserve valuable information while adopting the new harmonized approach.
In this context, the French national register SISERI has been collecting dosimetric data since 2005 with a level of detail sufficient to meet the ISO 24426 standard. SISERI’ s comprehensive approach ensures that collected data are robust and compatible with the harmonized methods proposed by ISO. This positions France as a key contributor to the effort of standardizing dosimetric data collection on a broader scale, facilitating better international collaboration and data comparability.
3.2 ESOREX average annual dose
Analysis of recent results collected in ESOREX Platform shows that France’ s average dose closely aligns with the overall international average for the years considered( Fig. 6). The trend remains stable until the COVID-19 crisis, which caused a decrease in the average dose. In the final year( 2021), the value increases, returning to the overall stable trend.
5 Discussion
In France, SISERI database constitutes the computerized national register of worker exposure, which has been enriched over the years. SISERI centralizes reference dosimetry for the longitudinal monitoring of all workers. Such a system is of major interest for the follow-up of workers’ exposure and epidemiological studies.
A SWOT analysis( strengths, weaknesses, opportunities, threats) of the SISERI system shows that: – In terms of strengths, SISERI is in accordance with the requirements of Directive 2013 / 59 / Euratom and offers a unified platform for all individual dosimetric data for exposed workers in France. Authorized stakeholders( e. g., radiation protection officers, occupational health services, etc.) have timely access to exposure records. It enables long-term tracking of individual workers’ radiation doses, critical for medical follow-up.
– In terms of Weaknesses, the system may be perceived as complex or non-intuitive by occasional users. SISERI requires rigorous data entry and validation procedures, which can be time-consuming for employers. SISERI is not interconnected with foreign systems, which can pose a problem in the event of intra-EU worker mobility.
– In terms of opportunities, increased stakeholder awareness and training can improve system adoption and data quality. Big data techniques could be leveraged to identify exposure trends, predict risks, and support preventive actions. A possible sharing with other occupational health monitoring systems should be also studied.
