It certainly is an interesting question, and some more info appeared in a
recent bulletin from ZL2VAL, quoted (in part) below:

By Astronaut Peggy Whitson:
Hey Guys,
[deleted]
One of the physiological aspects of flying in space is that we are
exposed to a higher radiation dose than folks on the ground. Luckily
for us, the magnetosphere that protects the Earth from this radiation
also has some beneficial effects for us too at just over 200 miles
above the Earth, but we still monitor exposure during the mission. We
have various types of radiation devices on board to monitor our doses
and the rate of accumulation, but there is one physical indicator that
is interesting. With my eyes closed, in a darkened sleep station,
before I have a chance to fall asleep, I will occasionally see streaks
of light flash across my eye(s). It looks like a meteor entering
Earth's atmosphere, only it's under my eyelids. These flashes are
high-energy particles that I'm seeing.
[etc,etc]

I've also read somewhere about the Concorde aircraft having to fly lower when
there are higher levels of radiation.
73, David.
