Cosmic radiation at flight altitudes rises when the sun is less active
Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun.

Radiation from space is constantly entering Earth's atmosphere, but how much of it reaches the altitudes used by commercial aircraft depends not only on height and location, but also on the activity of the sun. A new study based on high-altitude balloon measurements over southern Israel has mapped these changes through the atmosphere and found that radiation levels at aviation altitudes rise as solar activity falls.
