DOE-STD-3014-96

Leakpath Factor: The fraction of the radionuclides in the aerosol transported through some

confinement deposition of filtration mechanism.

Level of Concern: The concentration of an extremely hazardous substance in air above which

there may be serious irreversible health effects or death as a result of a single exposure for a

relatively short period of time.

Local Response or Damage: Penetration and spalling, scabbing, punching shear, and

perforation of building structural components (e.g., a wall or floor) that may not result in the

overall failure or collapse of the whole building structure.

Low Altitude (Victor) Route: The designated route between VOR or VORTAC stations for

aircraft flying at or below 5486 m or 5.5 km (18,000 ft) MSL.

Material at Risk (MAR): The amount of radionuclides available to be acted on by a given

physical stress.

Military Aviation: As used in this standard, the aircraft category pertaining to any aircraft

activity performed by the U.S. Air Force (USAF), U.S. Navy (USN), U.S. Marine Corps (USMC),

U.S. Army (USA), and the U.S. Coast Guard (USCG).

Missile: A general term used to denote both primary and secondary missiles. See also

"primary missile" and "secondary missile."

Near-Airport Analysis: The aircraft crash impact frequency analysis involving the airport flight

phases (takeoff and landing) for aircraft using airports within specified distances from a facility.

Nonairport Analysis: The aircraft crash impact frequency analysis involving aircraft in the

in-flight flight phase.
