Should we all be acting like cockroaches? Does a solar flare release gamma radiation?
A solar flare isn't just an explosion of hot gases. It pushes out waves of light all across the spectrum. That includes light we can't see -- including radiation in the form of X-rays and gamma rays. These rays can be dangerous to humans. Fortunately, the Earth's atmosphere absorbs most of these high-energy rays.
That's not to say everyone is in the clear after a solar flare. Humans in space or at high altitudes -- on board an airplane, for example -- could risk exposure to intense radiation. Short-term damage could include skin irritation. Long-term consequences might include an increased risk of developing skin cancer. But it's likely that any affected human would eventually recover from the exposure.
Electronics are also vulnerable to these rays. If high-energy rays were to hit a satellite, they could strip electrons from the metal components, ionizing them. As electrons break free, they could short out the electronics within a satellite. They could also create a magnetic field that would damage the satellite's systems. Some satellites have shielding to protect them from these rays, but many are still vulnerable.
