Effect of full <i>versus</i> open-palm hand shielding on worker radiation dose during manual restraint for small animal radiography.
Bibliographic record
Abstract
Open-palm hand shields are used by veterinary workers during manual restraint for small animal radiography. The objective of this study was to measure the reduction in scatter and primary beam radiation dose to the hand provided by a full glove and an open-palm shield, using a cadaver dog to simulate restraint by 2 workers of an awake, cooperative patient undergoing thoracic and abdominal radiography. Dose was measured for 30 exposures for each condition, for a total of 795 exposures. The mean percentage decrease in scatter radiation dose was 99.9% for a full glove and 40% for an open-palm shield. The mean percentage decrease in primary beam radiation dose was 98.4% for a full glove. To optimize worker protection, fully enclosing gloves should be used during manual restraint for radiography, and body parts should never be placed in the primary beam, even when shielded.

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.
