Introduction: The study aims to evaluate a personnel traceability tool based on QR codes in a contaminated zone during a nuclear and radiological (RN) event. Methods: A prospective, monocentric study was conducted to assess an IT tool using QR codes linked to individual identities, attached to uniforms and wristbands, utilizing a spreadsheet created with Microsoft® Office Excel. The QR codes were scanned by a reader connected to a computer at the single entrance and exit of the zone. Color codes indicated the duration of presence in the contaminated zone. To evaluate the tool, similar information was recorded manually. A satisfaction questionnaire regarding the speed of registration and tracking in the zone was administered at the end of the exercise. Results are expressed in counts and percentages, as well as mean ± standard deviation, with p < 0.05 considered significant for satisfaction comparisons using a Wilcoxon rank test. Results: No software malfunctions were reported. Satisfaction among the 25 participants was assessed on a scale of 10, with a score of 9 for the QR codes compared to 7.6 for manual registration and 7.2 for personnel tracking in the zone. Conclusion: In conclusion, this tool demonstrates its utility and effectiveness in managing a significant number of healthcare providers during an RN event. The interconnected use of this software by various services could reduce delays in the contaminated zone.
