Real-Time operating systems provide deterministic behavior for systems operating under strict deadline requirements. Beyond managing tasks and resources, operating systems offer a hardware abstraction layer that enables developers to concentrate on application logic instead of low-level hardware details. However, both systems with and without operating system support are vulnerable to ionizing radiation from sources such as cosmic rays, solar wind, electromagnetic interference, and other deep space phenomena. These radiation effects can lead to unintended, often catastrophic, failures ranging from system malfunctions to complete device breakdowns. Real-Time operating systems are commonly deployed in safety-critical applications including railway systems, military drones, medical devices and transportation systems in cars and airplanes; where even a minor failure could have dire consequences for human life.
