What is a radiation belt around the earth?

I read something that said the moon landing was a hoax because once you step out of the radiation belt you go into a solar storm which is let off from the sun. So basically anything living like a human cannot go to the moon because of the radiation. We do no have the technology yet to prevent us from dieing from it.What is a radiation belt around the earth?
Well you heard wrong. If you mean the Van Allen Belts. Here is a quote from the scientist who discovered them:



"The recent Fox TV show, which I saw, is an ingenious and entertaining assemblage of nonsense. The claim that radiation exposure during the Apollo missions would have been fatal to the astronauts is only one example of such nonsense." -- Dr. James Van Allen



As far as the argument about needing 6 feet of lead shielding, that is incorrect



"The "six feet of lead" statistic appears in many conspiracist charges, but no one has yet owned up to being the definitive source of that figure. In fact, six feet (2 m) of lead would probably shield against a very large atomic explosion, far in excess of the normal radiation encountered in space or in the Van Allen belts.



While such drastic measures are needed to shield against intense, high-frequency electromagnetic radiation, that is not the nature of the radiation in the Van Allen belts. In fact, because the Van Allen belts are composed of high-energy protons and high-energy electrons, metal shielding is actually counterproductive because of the Bremsstrahlung that would be induced.



Metals can be used to shield against particle radiation, but they are not the ideal substance. Polyethylene is the choice of particle shielding today, and various substances were available to the Apollo engineers to absorb Van Allen radiation. The fibrous insulation between the inner and outer hulls of the command module was likely the most effective form of radiation shielding. When metals must be used in spacecraft (e.g., for structural strength) then a lighter metal such as aluminum is better than heavier metals such as steel or lead. The lower the atomic number, the less Bremsstrahlung.



The notion that only vast amounts of a very heavy metal could shield against Van Allen belt radiation is a good indicator of how poorly though out the conspiracist radiation case is. What the conspiracists say is the only way of shielding against the Van Allen belt radiation turns out to be the worst way to attempt to do it!"



The missions flew through the thinnest portion of the belt very quickly. Total radiation was about equal to 1 x-ray.
This is the Van Allen Belt and it is a very effective shield from radiation, not only from the sun, but also bombarding us from all directions in space. A maximum radiation exposure set by NASA is 1 to 3 Sieverts. The amount of exposure to a person in space is quite high, and currently is thought by some as a show-stopper for an extended mission to the Moon or to Mars, but not a large threat for the Apollo missions. It has been estimated that round-trip travel to Mars would expose one to 0.3 to 0.6 Sieverts. But an 18 month's stay on Mars would expose the astronaut to an additional 0.4 Sieverts. Being on the lunar or Martian surface blocks off about half of the radiation exposure that a person receives in open space.

If there had been a major solar storm while astronauts were on the Moon in the Apollo missions, the radiation affects would likely have made the astronauts very sick in a short period of time. Otherwise, their exposure on the short lunar missions was well within bounds according to NASA guidelines.

And, you are correct, we do not have the technology, or at least a practical means, to artificially shield this radiation so we are presently limited to short forays, such as Apollo type missions.What is a radiation belt around the earth?
Its called the Van Allen Belt.

The belts would kill astronauts if they stayed there for too long but since the Apollo missions only ventured through them for a short period of time, this was not the case.



P.S. The belts could kill you NOT by cooking you but they do it if you are exposed for a long period of time and your cells start to die.
radiation your talking about comes from the sun, which we can protect our self's but only short periods at a time. the space station has built in defence to stop but if outside say the moon then only sort periods at a timeWhat is a radiation belt around the earth?

Not an issue.
