one of arguments by hoaxers is that astronauts would never be able to pass Van Allen radiation belts.
First of all, what are the radiation belts.
Those are belts around whole planet created by interaction of Earth`s magnetosphere and solar wind.
Solar wind is flow of energetic particles from Sun. Those belts were first discovered by James Van Allen.
There are two parts of them. Outer belt which is less dangerous and inner belt where is much more charged particles and especially protons.
It was also proved that there is antimatter in those belts but it is just such a low amount that we would not be able to use it anyway.
Well so hoaxers made up that if human being tried to cross this radiation belt it would kill him. The problem is that it would not, if he went fast enough.
Van Allen`s radiation belts are not stationary which means that there are days when there is more radiation and days when there is less.
Quess when NASA wanted Apollo to fly, huh?
So Apollo 11 went in angle of 30° from equator where the concetration of charged particles was smallest.
The fatal dose of radiation is 1000 rads while the astronauts got from the most dangerous part about 26 rads, which they survived.
This site more deeply explains it.
Most of the charged particles would not be even able to penetrate the space craft. Those which would, would give astronauts a dose about 50mSv. Which is something but it even counts with “higher” number of protons to not going through but all of them shooting the body.
