Radiation Response of Perfluorinated Polymer Optical Fibers (CYTOP) to Low Doses of X-Rays, Protons, and Neutrons
Bibliographic record
Abstract
The response of perfluorinated polymer fibers (PF-POFs) in X-ray, proton, and neutron irradiation was investigated for their potential application in clinical environments. Radiation-induced attenuation (RIA) in PF-POF increases linearly with dose and PF-POF was found to be highly sensitive to all the sources of radiation used. A sensitivity of 0.050 ± 0.003, 0.089 ± 0.005, and 0.065 ± 0.003 dB/m/Gy was recorded for 6 MV X-rays, 63 MeV protons, and 400 MeV neutrons, respectively, at a wavelength of 510 nm at room temperature. The PF-POF fibers also exhibit energy dependence—a useful feature in characterizing the depth dose in a proton beam. The high sensitivity of the fiber enables the development of distributed sensing in oncology and can be combined with other solid-state detectors in monitoring radiation dose in mixed radiation environments.

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.
