Space Radiation Sparks A Biological Cascade Of Cancer

What happened

Space Radiation Sparks A Biological Cascade Of Cancer, according to Universe Today. Deep space travel comes with a huge potential downside - radiation exposure that can kill an astronaut either quickly or slowly over time if not managed correctly. A new paper from researchers at Oklahoma State University and the University of Texas Health Science Center hopes to answer both questions, and while the causes of radiation they point out are complex, they also offer some potential solutions as well.

Scientists have long known that one of the main sources of cancers in deep space travelers (and even airline pilots) is Galactic Cosmic Rays (GCRs).

These are high-energy atomic nuclei that have been stripped of their electrons and accelerated by massive shockwaves from supernovae. But they are typically stopped by the protective blanket of Earth’s atmosphere before they can reach anyone on the ground. Video that describes some of the dangers of space radiation.
