A client-side JS engine was implemented to simulate decay using mono-exponential and piecewise multi-segmented models. Built-in JS functions were used to perform logarithmic and exponential operations. The tool's performance was validated against ion-chamber measurements from a thyroid phantom containing a pre-calibrated 131I capsule; moreover, measurement reliability was assessed. The phantom test showed a mean absolute error of 0.010 μSv/h for the mono-exponential model and 0.008 μSv/h for the multi-segmented model. The intraclass correlation coefficient (ICC) demonstrated excellent inter-observer agreement (ICC range: 0.998-0.999), while the mean intra-observer difference was 0.3% (SD = 0.2%; range: 0.1%-0.6%). By quantifying instrument-related error in advance, future studies may more confidently isolate biological variability, thereby supporting the robustness of patient-level interpretation and dose-prediction models.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"892-903"},"PeriodicalIF":0.8,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147499813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work is to extend the diagnostic reference level concept by formulating benchmarks stratified by breast thickness and system type, and to make these benchmarks readily available to facilitate ongoing real-time audit.Materials and method: After comparing the Facility diagnostic reference levels with the National one, the data set was divided into groups based on compressed breast thickness and system type. Benchmarks were established at the 95th percentile for individual categories, each combining a compressed breast thickness range with a system-type.Results: A Dose Management System was used to compare the median values of each individual system against the relevant benchmark. This enabled ongoing, pertinent comparisons of data in real-time.Conclusion: Comparison to the relevant benchmark helps to quickly identify systems requiring investigation and possible optimization. This transforms dose auditing into a proactive tool rather than a retrospective one.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"904-911"},"PeriodicalIF":0.8,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147504748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the professionals responsible for conducting X-ray examinations and their training in Ireland. An online survey was distributed to all practices registered with the Veterinary Council of Ireland. Data were collected on demographics, X-ray equipment, methods of exposure factor selection, confidence in adjustments, and knowledge of detector dose indicators. A total of 120 responses were received. Most clinics use digital systems and rely on technique charts. Many respondents showed limited understanding of detector dose indicators, with 40% reporting poor knowledge and nearly half unaware of their system's capabilities. Exposure factors were rarely adjusted, raising concerns about dose creep. Confidence was higher among less experienced staff. No strong association was found between post-qualification training and confidence. Findings highlight the need for improved training, continuous professional development, and guidelines to optimize practice.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"771-781"},"PeriodicalIF":0.8,"publicationDate":"2026-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13284610/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146166429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this framework, the accurate determination of the air-kerma rate is a critical step to ensure both calibration reliability and international traceability in radiation protection dosimetry. This study reports a comparative evaluation of two ionization chambers with different geometries: the PTW 32002 (spherical, 1 L) and the PTW 23361 (cylindrical, 30 cm3). Both were employed to characterize 137Cs and 60Co reference radiation fields at the CNESTEN calibration laboratory. The experimental results were compared against a theoretical benchmark provided by Monte Carlo simulations using the MCNP6.1 code to perform a comparative study with the measured values. The aim was to verify the installation's compliance with the inverse square law and to assess the metrological suitability of the two detectors. The results showed overall agreement between experiment and simulation, with deviations ranging from ~0.2% to 10.5%, depending on photon energy and source-to-detector distance. The spherical PTW 32002 chamber demonstrated greater stability in 60Co beams, while the cylindrical PTW 23361 exhibited better accuracy in 137Cs fields. These findings highlight the importance of chamber selection with respect to photon energy and dose rate, and confirm the compliance of the CNESTEN facility with international standards, thereby supporting reduced uncertainties and improved metrological traceability in calibration services.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"827-841"},"PeriodicalIF":0.8,"publicationDate":"2026-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147344943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
