Abstract

fetched live from OpenAlex

ABSTRACT: The Human Monitoring Laboratory (HML) at Health Canada collaborated with a nuclear industry facility to help characterize a contamination event with a male worker who showed contamination after a routine whole body count. Monte Carlo simulation was used to model the whole body counter (WBC) using an appropriately matched male voxel phantom. Ratios of the resulting modeled detector counting efficiencies were used to help determine the most likely area of contamination in or on the worker, thereby helping to approximate the potential dose received by the worker.

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 distilled prediction

Teacher imitation

Not 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.
