Factors affecting flight dose
The Earth's magnetic field and atmosphere serve as protective barriers, allowing only a small portion of cosmic radiation to reach the surface. The intensity of cosmic radiation exposure on an aircraft is influenced by factors such as flight distance, altitude, crossed geographic region, and the cosmic ray intensity at the time of flight.
✔As flight altitude increases, the shielding effect of the atmosphere weakens, leading to higher radiation exposure.
✔Most cosmic rays consist of charged particles, which are affected by the Earth's magnetic field. These particles are directed toward the Polar Regions, resulting in higher radiation dose rates at high latitudes.
✔The intensity of cosmic rays is also affected by the activity of sunspots, and rises and falls periodically with the 11-year solar cycle.
