Further considerations for the setting up of a low background whole-body counter for internal dosimetry at Waste Isolation Pilot Plant (WIPP) Carlsbad, NM, USA: transmitted photon component
Bibliographic record
Abstract
One of the further considerations in the present work, while setting up a low background whole-body counter (WBC) underground at the Waste Isolation Pilot Plant (WIPP) is to reduce the background in the energy region of interest <100 keV. The goal of the present work is to determine the adequacy of a chamber located underground at WIPP of dimensions 1.83 m × 1.22 m at the base, 1.83 m high, with 15 cm thick pre-world-war II steel shielding. The objective of the present work is to estimate the transmitted photon flux into this chamber for setting up the low background WBC. The transmitted photon flux is simulated with the GEANT code for an incident photon flux consisting only of 1461 keV photons. The results are discussed with respect to a detector of choice for detecting <50 mBq emitting photons in the energy region <100 keV.

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.
