Abstract

fetched live from OpenAlex

A moderator-type neutron survey meter, intended for radiation protection use at a nuclear power plant, was tested in five laboratory neutron fields, including neutron fields that resemble ones found in some reactor workplaces. Calibration constants (counts Sv(-1)) and responses (ratios of measured to reference values of ambient dose equivalent) were determined by measurement for each neutron field. Theoretical calibration constants were calculated for each field using a response function from the literature. These theoretical calibration constants were consistent with ones determined from measurement. Theoretical calibration constants were also calculated for several power-plant workplace neutron spectra. The range of calibration constants determined provided some insight into the amount of over-response and under-response that this particular survey meter would be likely to give when used in the intended workplace. Values for the calibration constant were suggested.

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.
