Since the astronauts need water to survive, why not line the spaceship with reservoirs of it to provide the shielding? Or does water not block space radiation well enough?
But then they’re drinking irradiated water, no?
Unless it’s really easy to remove the radiation safely, this doesn’t seem like the right solution.
Irradiated water is fine.
You're thinking of radioactive water, which is water with radioactive stuff in it.
Subjecting regular water to regular amounts of radiation is fine, even if it's high-energy gamma rays. If there's enough radiation to make water itself radioactive then you have bigger problems than radioactive water.
Ah yes, that’s the difference. Thanks!
