Abstract
This paper reports on the measurement of natural radionuclides in soil samples collected from southern Ontario, Canada. The mean activity concentrations in soil are 28, 28 and 641 Bq/kg for 226Ra, 232Th and 40K, respectively. Assuming activity concentrations in masonry materials such as brick and concrete are similar to soil in the surrounding area, the activity concentration index for masonry materials of Southern Ontario origin is estimated as 0.45, ranging from 0.15 to 0.83. The results indicate that the annual effective dose from exposure to gamma radiation in buildings constructed using masonry materials of southern Ontario origin for all structures (floor, ceiling and walls) would be <1 mSv.

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
