decontaminates; it can be decontaminated, and it is compatible with individual
protective equipment.
• Hardness. The capability of material to withstand the materiel -damaging
effects of NBCC and relevant decontamination.
• Decontamination. The process of making personnel and materiel safe by
rendering harmless or removing radioactive, chemical, or biological material.
• Compatibility. The capability of a system to be operated, maintained, and resupplied
by persons wearing individual protective equipment, in all climates
for which the system is designed, and for the period specified in the
operational requirements document.

nuclear device.

Nuclear
Environment
The environment, which results from the detonation of nuclear weapons. Some
components of this environment are directly emitted by the nuclear weapon and
other collateral effects are created by the interaction of the emitted nuclear
radiation with the earth’s atmosphere, the earth’s surface and the earth’s
magnetic field. The nuclear environment consists of radiation, blast, shock,
thermal, electromagnetic pulse (EMP), emissions from radioactive debris, trapped
electrons, and disturbances to the atmosphere and to the propagation paths for
radar and communications. The nuclear environment exists in the
exoatmospheric, atmospheric and ground BMD operational regimes.
Nuclear
Hardness
A quantitative description of the resistance of a system or component to
malfunction (temporary and permanent) and/or degraded performance induced
by a nuclear weapon environment. Resistance to physical quantities such as
overpressure, peak velocities, energy absorbed, and electrical stress measures
hardness. Hardness is achieved through adhering to appropriate design
specifications and is verified by one or more test and analysis techniques.
Nuclear
Radiation
Particulate and electromagnetic radiation emitted from atomic nuclei in various
nuclear processes. The important nuclear radiations, from the weapons standpoint,
are alpha and beta particles, gamma rays, and neutrons. All nuclear
radiations are ionizing radiations, but the reverse is not true; x-rays, for example,
are included among ionizing radiations, but they are not nuclear radiations since
they do not originate from atomic nuclei. (See Ionizing Radiation and X-Rays.)
Nuclear
Survivability
Characteristics
A quantitative description of the system features needed to meet its survivability
requirements. Such system features include those design, performance, and
operational capabilities used to limit or avoid the hostile environment,
architectures that minimize the impact of localized damage to the larger wartime
mission, as well as physical hardening to environment levels, which cannot be
mitigated otherwise. Survivability characteristics include proliferation, redundancy,
avoidance, reconstitution, deception, and hardening.
