Q. Radiation hardening is used in design of artificial satellites, spacecraft, military aircraft, nuclear power stations, and nuclear weapons for which of the following purposes?
Answer: Protection from radiation damage
Notes: Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
