Total Ionizing Dose
Total Ionizing Dose (TID) is the measure of the amount of ionizing radiation that a material or electronic component has been exposed to over time. In space and astronautical engineering, TID is a critical factor in the design and operation of spacecraft and satellites, as exposure to ionizing radiation can cause degradation and failure of electronic components. TID can be caused by a variety of sources, including solar flares, cosmic rays, and trapped radiation in the Earth's magnetic field. Engineers must take into account the expected TID levels for a given mission and design electronic components and systems that can withstand the expected radiation exposure. TID testing is also performed on components and systems prior to launch to ensure that they will function properly in the space environment.
