Nuclear Industry Applications of Si-Diode Based High Gamma Dose Rate Detectors
Bibliographic record
Abstract
AECL has developed and deployed several high gamma radiation field measurement and profiling systems based on commercial off-the-shelf (COTS) silicon diode sensors and components. These systems have been useful in a number of applications including radiation survey of a medical radioisotope production hot-cell, liquid level measurement in a highly radioactive tank, identification of waste location inside nuclear waste storage structures, imaging of reactivity devices inside a shut-down nuclear reactor, and for scanning and imaging highly radioactive reactor components inside a hot-cell in support of an industrial surveillance project. The measurements ranged from 100 uGy/h (10 mRad/h) to 10 kGy/h (1MRad/h), which covers typical radiation fields in hazardous nuclear facilities. This paper summarizes the development and characterization of the Si-diode based detector system, and describes its performance in a variety of applications.Copyright © 2012 by ASME

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
