Radiation Safety in the Catheterization Laboratory: Current Perspectives and Practices.
Bibliographic record
Abstract
BACKGROUND: There is great variability in radiation safety practices in cardiac catheterization laboratories around the world. METHODS: We performed an international online survey on radiation safety including interventional cardiologists, electrophysiologists, interventional radiologists, and vascular surgeons. RESULTS: A total of 570 responses were received from various geographic locations, including the United States (77.9%), Asia (7.9%), Europe (6.8%), Canada (2.8%), and Mexico and Central America (2.1%). Most respondents (73%) were interventional cardiologists and 23% were electrophysiologists, with 14.4 ± 10.2 years in practice. Most respondents (75%) were not aware of their radiation dose during the past year and 21.2% had never attended a radiation safety course; 58.9% are "somewhat worried" and 31.5% are "very worried" about chronic radiation exposure. Back pain due to lead use was reported by 43.0% and radiation-related health complications including cataracts and malignancies were reported by 6.3%. Only 37.5% of respondents had an established radiation dose threshold for initiating patient follow-up. When comparing United States operators with the other respondents, the former were more likely to attend radiation safety courses (P<.001), wear dosimeters (P<.001), know their annual personal radiation exposure (P<.001), and have an established patient radiation dose threshold (P<.001). They were also more likely to use the fluoro store function, under-table shields, leaded glasses, ceiling lead glass, and disposable radiation shields, and were more concerned about the adverse effects of radiation. CONCLUSIONS: Radiation safety is of concern to catheterization laboratory personnel, yet there is significant variability in radiation protection practices, highlighting several opportunities for standardization and improvement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
