Re: Were the apollo lunar landings faked?
Van Allen radiation belt - Wikipedia, the free encyclopedia
Read through that, and then tell me how the Van Allen belt was dangerous to the Apollo astronauts.
Quote:
During Project Apollo, astronauts traveled through the Van Allen belts on both the outbound and return trips to the moon. The crews spent only limited time in transit in the region, and consequently the radiation exposure was limited. The Apollo 14 crew recorded the highest Van Allen belt exposures during their February 1971 mission, but the crew's short-term exposure was still within acceptable levels. Future manned missions beyond earth orbit must also transit the Van Allen belts, but these missions will be shielded and hardened for much longer-duration exposure to cosmic rays and solar wind.
An object satellite shielded by 3 mm of aluminium will receive about 2,500 rem (25 Sv) per year.
