Ionising radiation the big danger to astronauts

NASA says that not only does space radiation potentially put astronauts at greater risk of radiation sickness, but an “increased lifetime risk for cancer, central nervous system effects, and degenerative diseases.”
Astronauts in space are exposed to the radiation equivalent of 150 to 6,000 chest x-rays https://www.revelstokereview.com/news/morning-start-astronauts-in-space-are-exposed-to-the-radiation-equivalent-of-150-to-6000-chest-x-rays/ May 28, 2021
As noted by NASA, radiation is a type of energy that is emitted in the form of rays, electromagnetic waves and/or particles. Radiation can be seen as visible light or felt as infrared radiation. However, some forms of radiation, like x-rays and gamma rays, are not visible.
Space radiation differs from the type of radiation experienced on Earth because intergalactic radiation “is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light – eventually, only the nucleus of the atom remains.”
So how much space radiation are astronauts exposed to? They’re exposed to “ionizing radiation with effective doses in the range from 50 to 2,000 mSv. 1 mSv of ionizing radiation is equivalent to about three chest x-rays. So that’s like if you were to have 150 to 6,000 chest x-rays.”
With that being said, NASA says that not only does space radiation potentially put astronauts at greater risk of radiation sickness, but an “increased lifetime risk for cancer, central nervous system effects, and degenerative diseases.”
