A decade of national reporting data, presented at the European Congress of Radiology 2026, offers new insight into radiation safety in diagnostic imaging. The research indicates that systematic monitoring of X-ray deviations strengthens safety culture and reduces serious incidents.
Ensuring strong radiation safety is a priority in radiology. In Finland, radiation safety deviations during X-ray examinations must be reported to the Radiation and Nuclear Safety Authority (STUK). These reports allow institutions to monitor errors and improve clinical practice.
Researchers analyzed deviation reports submitted to STUK between 2015 and 2024. Approximately 270 significant and 12,650 less significant deviations were reported. Importantly, no severe radiation safety incidents have occurred since systematic reporting began.
Patient exposures remained below 100 mSv, occupational exposures below 1 mSv, and unintended foetal exposures below 40 mGy. The most frequent deviations involved failed examinations due to technical issues or human error.
Structured reporting systems are crucial for maintaining high radiation safety standards. Finland will expand reporting in 2025 to include preventive actions taken. Experts suggest similar frameworks could improve radiology safety internationally.
