Exam Questions and CORRECT Answers
Acute Radiation Sickness (ARS) - CORRECT ANSWER - Illness caused by a large dose
of radiation in a very short period of time. The radiation dose must be external and penetrating
and cover almost the entire body. Symptoms include nausea, vomiting, and diarrhea, but they
may not develop for hours or days after the exposure.
Alpha Paricles - CORRECT ANSWER - Particulate material that quickly loses its energy
as it travels through the air.
Atom - CORRECT ANSWER - The smallest particle of an element that can exist either
alone or in combination with another element.
Beta Particles - CORRECT ANSWER - Particulate material that loses energy more slowly
than alpha particles.
BLAST PRESSURE - CORRECT ANSWER - Includes a positive-pressure phase and a
negative-pressure phase. Positive pressure moves rapidly from the point of origin of the
explosion, pushing the air away from it and delivering violent force to everything in its path.
Negative pressure is a vacuum/suction phase which accounts for much of the debris near the area
of greatest damage.
CBRNE - CORRECT ANSWER - Chemical, Biological, Radiological, Nuclear, and
Explosive.
CHEMICAL WARFARE AGENTS - CORRECT ANSWER - Chemical substances that
are intended for use in military operations to kill, seriously injure, or incapacitate people through
physiological effects. These agents can exist in solid, liquid, or gaseous states.
COLD ZONE - CORRECT ANSWER - Also called the clean zone, support zone, or green
zone. Contains the Incident Command Post (ICP) and other support functions deemed necessary
to control the incident.

properties which, if not properly controlled, present a potential hazard to human health and
safety, infrastructure, and/or their means of transport.
DOMESTIC TERRORISM - CORRECT ANSWER - Activities that involve acts
dangerous to human life that are a violation of the criminal laws of the United States or of any
state; appear to be intended to intimidate or coerce a civilian population, to influence the policy
of a government by intimidation or coercion, or to affect the conduct of a government by mass
destruction, assassination, or kidnapping; and occur primarily within the territorial jurisdiction of
the United States.
DOSE RATE - CORRECT ANSWER - The amount of radiation energy absorbed by a
person.
EXCEPTED PACKAGE - CORRECT ANSWER - Used when transporting low-level
radioactive materials, such as smoke detectors.
EXPOSED - CORRECT ANSWER - Term used to indicate when radiation energy reaches
a person.
EXTERNAL CONTAMINATION - CORRECT ANSWER - Term used to describe when
a hazardous material is physically attached to a person's skin and/or hair.
EXTERNAL EXPOSURE - CORRECT ANSWER - Term used to describe when a
hazardous material reaches a person from sources outside the body.
EXTREMELY HAZARDOUS SUBSTANCES - CORRECT ANSWER - Defined by the
United States Environmental Protection Agency (EPA) as chemicals that must be reported to the
appropriate authorities if released above the threshold reporting quantity listed in the Superfund
Amendments and Reauthorization Act (SARA) Title III.
