Abstract
INTRODUCTION: The medical director of the pediatric intensive care unit (PICU) selected a collection of pediatric chest X-rays for a clinical audit. As an unrelated activity during the performance of this audit, the frequency of adult fingers visualized on the PICU chest X-rays was documented. METHODS: A clinical audit of 439 PICU chest X-rays was performed. The visualization of adult fingers on the radiographs was categorized into those fingers directly in the X-ray beam and those seen only in the partially coned area of the images. RESULTS: There were 43 instances (9.8%) in which adult fingers were directly exposed to the X-ray beam. Additionally, in 23 instances (5.2%), adult fingers were seen only in the partially coned area of the image. DISCUSSION: Professional standards of practice and radiation biology publications support the need to avoid occupational radiation exposure. Occupational health and safety and radiation safety regulations stipulate that operators of an X-ray emitting device, or technologists assisting in the operation of an X-ray emitting device, must distance themselves from the primary beam (minimum of 3 metres) during X-ray exposure. All attempts must be made not to expose other individuals during the acquisition of clinical images. These policies and practice standards must be reinforced to minimize the exposure of medical radiation technologists and other medical staff to radiation.

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.
