Biological agents dispersal

Mechanisms and conventional explosives that terrorists could use to disperse nuclear, chemical, or biological agents... 

Mechanisms by which terrorists could disperse various types of nuclear, chemical, and biological agents... 

Biological agents also provide terrorists with a wide variety of alternatives for dispersion. For example, rather than using explosives to disperse biological agents, these materials could potentially ... 

For biological attacks, the time lag between exposure and symptoms and the current lack of reliable, deployable sensors suggest that a model-based system formulated from the perspective of tracking agent dispersion and distribution and the location of the exposed individuals may be the most useful approach for some time. 

People and/or animals can also act as dispersion mechanisms (vectors) for the spread of biological agents. For infectious agents spread initially in an aerosol cloud, exposed personnel act as dispersive cells, moving randomly in many different directions and over great distances. This situation takes the modeling problem beyond simple physics, since personnel movement is driven by many factors, most of which cannot be modeled in any sort of predictive sense. 

Biological Weapon. A biological weapon is a weapon that projects, disperses, or disseminates a biological agent or insect vectors of biological agents. 

Biological Weapon - An item of material that projects, disperses, or disseminates a biological agent including arthropod vectors. Blepharospasm - Uncontrollable winking caused by involuntary contraction of an eyelid muscle. BLPS - Ballistic / Laser Eye protection. Bradycardia - Abnormally slow heartbeat. Broken Arrows - An accident involving nuclear weapons. While it is almost impossible for the warhead to accidentally detonate, the accident may spread radioactive contamination over a wide area.
