Abstract

fetched live from OpenAlex

The development of primary standards of absorbed dose for electron beams has lagged somewhat the development of photon beam standards. However, this has not limited the diversity of designs, or the range of applications. This review describes the state-of-the-art in electron beam standards as practised today in a number of primary standards laboratories and research institutions around the world. The devices detailed cover electron energies from 80 keV to 25 MeV and doses from 1 Gy to tens of kilogray, although the focus of the majority of research is on dosimetry for radiation therapy.

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.

Not 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.
