THE CANADIAN NATIONAL CALIBRATION REFERENCE CENTER FOR BIOASSAY AND IN VIVO MONITORING: AN UPDATE
Bibliographic record
Abstract
The Canadian National Calibration Reference Center (NCRC) for Bioassay and In Vivo Monitoring is part of the Radiation Protection Bureau, Health Canada. The NCRC operates three performance testing programs that are designed to confirm that workplace monitoring results are accurate and provide the necessary external verification that is part of a comprehensive quality assurance program. The NCRC performance testing programs cover the in vitro, in vivo, and internal dosimetry parts of Canadian facilities' radiation protection programs. The internal dosimetry performance testing is a new addition to the performance testing suite. This summary also describes the recent reorganization of the NCRC.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
