Radiation dose rates, seen in this NAIRAS model, increase with altitude and latitude and can vary from hour to hour. Rates for Nov. 14, 2012, 20:00-21:00 GMT are shown above. Warmer colors indicate higher amounts of radiation. Credit: NASA/NAIRAS

NASA scientists studying high-altitude radiation recently published new results on the effects of cosmic radiation in our atmosphere. Their research will help improve real-time radiation monitoring for aviation industry crew and passengers working in potentially higher radiation environments.Imagine you’re sitting on an airplane. Cruising through the stratosphere at 36,000 feet, you’re well above the clouds and birds, and indeed, much of the atmosphere. But, despite its looks, this region is far from empty.

Just above you, high-energy particles, c...
