None dead. None sick.
The article says 1000 mSv single dosage that causes radiation sickness. So 432 mSv in a year is not so scary from that perspective. Safer to say 400 mSv in a single shot begins to be a risk and in a year is four times higher than the no risk level of 100 mSv.
Don't let them scare you. Radiation is not keeping us from going to and living on mars.
