Radiation and the International Space Station: Recommendations to Reduce Risk (2000)

[About coronal mass ejections:] Since Earth's magnetic field shields ISS from solar particle radiation during most of its orbital path, the actual exposure will depend on the orbital location of ISS when radiation levels peak.

Aboard the space station, improving the amounts and types of
shielding in the most frequently occupied locations, such as the
sleeping quarters and the galley, has reduced the crew’s exposure
to space radiation. Materials that have high hydrogen contents,
such as polyethylene, can reduce primary and secondary
radiation to a greater extent than metals, such as aluminum.
[...]
Active monitoring of space radiation levels also can help reduce
the levels of radiation an astronaut receives by helping the
astronauts locate the best-shielded locations on the station.
The monitoring also serves as a warning should radiation levels
increase due to solar disturbances. Following a healthy diet and
lifestyle, including the use of antioxidants following radiation
exposure, should also reduce risks.
