And when it comes to space, ISS is a pretty benign environment - shirt
sleeves, low radiation, etc.
You want hostile, go to Europa - 1 Rad/second kinds of dose plus LOTS of
high energy particles from the interaction with Jupiter.
That sort of brownish spot on Europa¹s ice?  That¹s a radiation burn.
