Radiation sickness occurs around 200 to 1000 'rads'w/in a few hrs. The Apollo 11 crew were within the belts for less than 2 hrs, an estimated 18 rads. The average dose of radiation over the 12-day mission was 0.18 rads - similar to a chest X-ray. https://www.bbc.co.uk/newsround/48774080 https://science.nasa.gov/biological-physical/stories/van-allen-belts/
