Intrinsic Radiation Damage Tolerance as a Structural Admissibility Condition for Functional Materials

Description (Abstract) This work establishes intrinsic radiation damage tolerance as a necessary structural admissibility condition for materials and material systems that claim functionality, durability, reliability, or safety under ionizing radiation, particle flux, or high-energy exposure. The analysis is non-constructive and does not disclose any specific compositions, crystal structures, defect-engineering strategies, annealing protocols, shielding assumptions, or fabrication methods. Instead, it formalizes a boundary condition under which a claimed material identity must preserve functional integrity under relevant radiation exposure as an intrinsic property, rather than through periodic healing, replacement cycles, shielding reliance, or operational avoidance. This condition constrains patentability at the level of enablement, inventive step, and industrial applicability and applies uniformly across radiation-exposed domains. This document functions as prior art defining admissibility, not as a technical teaching.
