Abstract
This work evaluates the entrance skin dose (ESD), the body organ dose (BOD) and the effective dose (E) for chest X-ray exposures of paediatric patients. Two Moroccan university hospitals in Rabat, composed of two departments, and one in Casablanca with one paediatric compartment has been considered. For reasons of confidentiality, the departments are named A, B and C. Patients were divided into four age groups: 0-1, 1-5, 5-10 and 10-15 y, so that the results could be compared with previous published data found in the literature. The results have been calculated with the use of the Dose Cal software. Results of mean ESD for the age interval 1-5 y and antero-posterior (AP) projection are: 162 µGy for hospital A, 91 µGy for hospital B and 105 µGy for hospital C. The diagnostic reference levels (DRLs) of 100 µGy for this age range is exceeded in hospital A, while in the other two hospitals results were within the DRL and comparable with the results found in Brazil, Soudan, Nigeria and other radiological centres inpean Countries. The results of BOD and E showed that for the three departments, the BOD varies in the same proportion as the ESD. The highest values are those of hospital A. For the PA examination, the dose is reduced compared with the AP projection, especially for sensitive organs.

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 it
