What is Radiation hardening?
'''Radiation hardening''' is the designing of [[electronic]] parts and systems so they can withstand the damage done by [[ionizing radiation]]. Such radiation occurs in [[outer space]] and when flying at high altitudes in the [[Van Allen radiation belts]]. They also occur in [[nuclear explosion]]s, and near [[nuclear reactor]]s and other sources of radiation. There are many techniques which can achieve hardening. The '''MRAM''', [[Magnetoresistive random access memory]], is proposed as the solution to long-lasting electronic memory. This is the heart of radiation resistance, because if the system memory is undamaged, the system can be [[Booting|rebooted]]. {{science-stub}} [[Category:Electrical engineering]]
