Abstract
In this article I examine the life of an artifact, the Theratron Junior, a sleek green radiotherapy machine from 1956 displayed in a permanent exhibit at the Canada Science and Technology Museum. It is currently seen through the lens of Canadian innovations, but the Theratron Junior brims with features and history that touch on several other historical narratives—scientific, commercial, labour, aesthetics and patient experience. The striking “sea foam” green paint, for example, has inspired an independent exhibition at the museum on the colour green in twentieth-century medicine. In addition, research into the former life of the specific machine on display (serial no. 15 from 1956), including the people who made and used it, has produced a reinvigorated artifact biography that enriches and challenges conventional narratives from Canada’s early atomic era. The lessons from careful artifact studies are readily clear—we are missing opportunities by taking for granted the most familiar items on our museum floors.

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
