Editing Radiation hardening (section)

===Notes===
# Nuclear hardness may be expressed in terms of either [[Electromagnetic compatibility#Introduction|susceptibility]] or [[vulnerability (computing)|vulnerability]].
# The extent of expected performance [[Degradation (telecommunications)|degradation]] (''e.g.,'' outage time, [[data]] lost, and equipment damage) must be defined or specified. The environment (''e.g.,'' radiation levels, overpressure, peak velocities, energy absorbed, and electrical stress) must be defined or specified.
# The physical attributes of a system or component that will allow a defined degree of [[survivability]] in a given environment created by a nuclear weapon.
# Nuclear hardness is determined for specified or actual quantified environmental conditions and physical parameters, such as peak radiation levels, overpressure, velocities, energy absorbed, and electrical stress. It is achieved through [[design specification]]s and it is verified by test and analysis techniques.
