概要	Radioactive waste classification is a systematic framework for categorizing radioactive materials based on activity, heat generation, and long-term hazard potential, developed by the IAEA. It stratifies waste into classes (exempt, very low-level, low-level, intermediate-level, high-level) to determine appropriate management pathways—from near-surface disposal to deep geological repositories—ensuring environmental protection and regulatory compliance.	Radiation protection optimization is a systematic approach to design and manage exposure reduction strategies using risk-benefit analysis, codified by the ICRP in the principle of As Low As Reasonably Achievable (ALARA) in 1977. By balancing radiation dose reduction against cost, effort, and societal benefit, it guides practical protection decisions in medical imaging, occupational settings, and environmental remediation.
