That would be equivalent to eating ~13,690 bananas. It is not an accumulative dose though, so you would have to stuff them a bit.
Radiation workers in the US are allowed to get 50,000µSv per year, so it certainly is a relevant exposure. But if they only stay two weeks, it would still be just about one chest X-ray.
Would be more concerned about these "large solar particle events".
