Chemical weapons include nerve agents, blister agents, blood agents, choking agents, incapacitating agents or any toxic industrial chemical (TIC) utilized as a weapon.
Biological weapons include pathogens such as bacteria, viruses, rickettsia, yeasts, fungi, toxins, vectors, and endogenous biological regulators used as a weapon.
Radiological weapons include radiological dispersal devices which is any explosive device utilized to spread radioactive material; or a simple radiological dispersal device which is any act or container designed to release radiological material as a weapon without an explosion.
Nuclear weapons include traditional nuclear bombs (e.g. suitcase nukes) and improvised nuclear devices which are explosive devices designed to cause a nuclear yield.
Weaponization is the deliberate processing, preparation, packaging, or synthesis of any substance for use as a weapon or munition. “Weaponized agents” are those agents or substances prepared for dissemination through any explosive, thermal, pneumatic, or mechanical means.
