Abstract
2002 DRDC Ottawa (and formerly as DREO) has participated in two NATO-sponsored and one TTCP-sponsored dosimetry intercomparisons. The SILENE International Accident Dosimetry Intercomparison Exercise at Valduc, France in June 2002 coincided with DRDC Ottawa work designed to refine its proposed criticality dosimetry system (consisting of Rh foils for neutron dosimetry and the combination of CaF2:Mn and A120 3 TLDs for gamma-ray dosimetry). In addition, DRDC Ottawa has recently substantially expanded its efforts in radiation dosimetry- and this intercomparison offered a unique opportunity to showcase and quantify these new capabilities. The results presented herein conclusively show DRDC Ottawa's capabilities to measure accurately criticality fields. In particular the neutron dosimetric work produced near real-time results-consistent with the target doses. The Rh foils clearly demonstrated their arguably most important feature- near invariability of response for all conceivable fission-like spectra. The gamma-ray dosimeters also showed their efficacy.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
