High-activity waste is very dangerous if not shielded and managed correctly, but it is produced in relatively small volumes and tracked under strict rules. Many toxic chemical wastes, on the other hand, do not decay over time. A proper comparison must distinguish between toxicity, duration, volume, environmental mobility, and regulatory control. The absolute statement 'the most dangerous' cannot be unambiguously substantiated.
