The construction of transportable radioactive concrete sources for portable and airborne gamma-ray spectrometers calibration is described in some detail. The eight concrete sources were constructed following the model adopted by the Geological Survey of Canada and have the dimensions of 1 m x 1 m x 0,3 m. Two sources containing only the bulk concret mass were designed for background radiation observations. Three sources are particulary enriched in one of the three main natural radioactive elements (K, U, Th) with traces of the other two. The remaining three sources contain varying amounts of the radioactives elements.

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.
