LES ACTIVITÉS NUCLÉAIRES : RAYONNEMENTS IONISANTS ET RISQUES POUR LA SANTÉ ET L’ENVIRONNEMENT Finally, for on-site transport operations, 9 events – rated level 0 on the INES scale – were reported in 2025. This significant increase, compared with the only event declared in 2024, reflects operators' growing awareness of the importance of declaring a significant event. Sectors concerned by these events As in the previous years, most of the significant events notified concern the road transport of radiopharmaceutical products (close to 20%). This figure has been constantly dropping for several years, owing to improved monitoring of carriers by the carriage commission agents. Unlike last year, the number of significant events relating to the transport of gamma radiography equipment fell sharply (6.3% compared with 22.3% in 2024), which could be explained by the fact that the ASNR's recurrent regulatory reminders to users and suppliers of this type of equipment were taken into account, albeit belatedly. On the other hand, the year 2025 saw an upsurge in reports of events relating to the transport of uranium compounds – made up exclusively of natural uranium for 2025 (15% compared with 7.8% in 2024). As for the events rated level 1 on the INES scale, these involved: ∙non-compliance with the FCC packaging user manual, classified at INES level 1 because of the failure to implement a new method for tightening the screws on FCCs (packaging used to transport fresh fuel) more than nine months after it was sent by the engineering departments to the operators; ∙the transport of a package of radiopharmaceuticals by an unauthorised person, classified at INES level 1 for a series of breaches of regulations (see Highlight No. 2 on the ASNR's summons of Warning Euromatic); ∙the other events classified at INES level 1 related to the theft of X-ray fluorescence analysis equipment containing a radioactive sealed source, intended to detect lead in paint, one of which was recovered a few days after its theft. These events were classified at INES level 1 because of the loss, even temporary, of the source's location. It should be noted that such events may be classified as Significant Radiation Protection Events (ESRs) or Significant Transport Events (EITs). None of these four level 1 events on the INES scale had any consequences for the workers, population, or environment.
