Biologic agents that are the deadliest substances known to humans; they include botulinum toxin and ricin.

37
Q

neutron radiation

A

The type of energy that is emitted from a strong radiologic source, involving particles that are among the most powerful forms of radiation; the particles easily penetrate through lead and require several feet of concrete to stop them.

A

The release of an agent after exposure—for example, from a person’s clothes that have been exposed to the agent.

A

A blistering agent that has a rapid onset of symptoms and produces immediate, intense pain and discomfort on contact.

66
Q

viral hemorrhagic fevers

A

A group of diseases caused by viruses that include the Ebola, Rift Valley, and yellow fevers, among others. This group of viruses causes the blood in the body to seep out from the tissues and blood vessels.

68
Q

volatility

A

How long a chemical agent will stay on a surface before it evaporates.
