    I'v been haveing an on going argument about this, the other guy says the Van Allen belt protects us from radiation, and to travel beyond it would mean certain death, thus the lunor landing could not have happened. But I say the van allen belt is a ring of radiation surrounding the planet, held in place by the earths gravitational pull and because its so narrow, and the with the speed they would have been doing the exposure would have been minimal.

    Taken from here
    Radiation was too high - Van Allen belts and solar storms
    The hoax proponents consistently exaggerate the effects of radiation in space. Radiation was a definite concern for NASA before the first spaceflights, and they invested a great deal of research in it before flying the first astronauts into space. The most dangerous part of the journey to the moon for radiation exposure was during the passage of the spacecraft through the Van Allen belts. This is a zone from aobut 1000 kilometers up to about 20000 kilometers. The Apollo missions flew through this zone at very high speed - outbound starting around 40,000 kph and inbound at about the same speed. They spent a few hours within the Van Allen belts and estimates of the total exposure during their passage is about 2 rems (the equivalent of about 100 chest x-rays or about 40% of the maximum permissible does of radiation according to OSHA standards). Doses of 100-200 rems cause a person to experience nausea several hours after exposure and fatal doses occure above about 300 rem. Solar flares were a concern as well, but typical doses due to flares that the Astronauts were exposed to were only a few rem. The crews wore dosimeters which were read back roughly daily during the flights.

    Basically put, your friend has it ar5e about face. The Van Allen belt is (as you say) a ring of radiation. A google search on the term will come up with enough info on that.

    As for the danger of radiation outside the VAB, ask your mate where he found that information, and who actually has scientifically measured it. Oh - hang on - that would be the same people he's saying faked the moon landing.

    Which doesnt make sense. Why would they not keep a consitent story :)
