Assessment of minimal-separation criteria in a 50-m corridor
Bibliographic record
Abstract
In a hospital, portable radio frequency (RF) sources can cause field strengths in excess of immunity levels of some critical-care medical devices, unless appropriate minimal separations are maintained between sources and devices. This paper examines the risk of medical-device interference due to a 1900 MHz cell phone transmitting near one end of a 50-m hospital corridor. Detailed maps of corridor field strength are calculated, using geometrical optics, in planar cross-sections at various heights above the floor. For a device of given immunity, the interference risk is quantified from the ratio: (number of locations with immunity exceeded)/(total number of locations). Minimal-separation distances (separations ensuring that transmitter fields fall below a given device's immunity level) obtained assuming free-space propagation are compared to minimal separations specified in the current IEC standard for medical electromagnetic compatibility (EMC). It is concluded that using the separations of this standard effectively reduces the interference risk to zero.

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.
