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. But what exactly does that mean, and is there any way to handle it other than sticking more and more protective layers between the squishy biological systems inside a spacecraft and the radiative void of deep space? 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.
