 We know for a fact the risk is not high because the Apollo astronauts went through the Van Allen belts and then went beyond where they're even more exposed to radiation, and they survived for the two weeks they were in space, two or three weeks. And this is only going to be for a day or two. But they now have better sensors and data to figure out what small influences they'll have, and that'll help tell something about long-term effects as well.
