Large-body radiation doses following radioiodine therapy
Bibliographic record
Abstract
In accordance with the recommendations of the International Radiological Protection Commission, the current maximum acceptable radiation dose limits for members of the public have been reduced to 1 mSv in the United States, Canada, and European Union countries including the United Kingdom. This has had a significant impact on radiation protection guidelines for contacts of patients treated with 131I. Many previous recommendations have relied upon models which may overestimate dose rates at short distances. We therefore undertook measurements of 131I dose rates using adult and infant phantoms that more accurately reflected true geometry. Effective dose calculations and patient contact restrictions were then derived from these direct dose measurements. Doses received by the adult phantom were measured at three distances (contact, 1.0 m, 2.0 m) and doses received by the infant phantom were measured at contact in two orientations (adult cradling infant over shoulder and at waist). The doses measured were significantly lower than previously predicted for the adult and infant phantom. Our measurements suggest that patient contact restrictions could be made less stringent than those currently in widespread use.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
