Design Blueprint: A Polarised-Film Radiation Dosimeter: Computed Dose Response, Minimum Detectable Dose and Range of a Spin-Polarised Film Badge

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24129862): Radiation dose in a polarised material leaves a permanent record: ionising events destroy polarisation in proportion to dose, and a polarimetric readout afterwards recovers the accumulated exposure. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
