Skyrad 0 #76 May 18, 2004 I don't belive that man walked or even landed on the moon in 1969. Sure theres all the picture debate but my reason for not beliving is simple science. How did they get through the Van Allen belt with only bacofoil to protect them? TWICE! To shield from that kind of radiation the walls of the craft would have to have been made of six foot thick lead to attenuate the quality and intensity of radiation in the belt. Did they leave Earth? Yes. Did they land on the moon? No way.When an author is too meticulous about his style, you may presume that his mind is frivolous and his content flimsy.

Harksaw 0 #77 May 18, 2004 From the BBC: Quote Radiation from the Van Allen belt would kill any astronaut that spent enough time there. But the Apollo craft didn't spend long enough there for the astronauts to get a fatal dose. NASA point out that astronauts on the Space Shuttle still pass through this belt with no ill effects.

billvon 2,991 #79 May 19, 2004 >How did they get through the Van Allen belt with only bacofoil to >protect them? TWICE! How do you survive CAT scans? Because the intensity is low and the duration is limited. The Van Allen Belts contain many different levels. There are two primary ones - a layer of high energy protons and a layer of high energy electrons. Only a few of the very highest energy layers are able to punch through the aluminum of the spacecraft. Electrons and protons, unlike the photons that make up cosmic radiation, are more easily stopped by thin shielding. The Apollo astronauts transitioned through that region fairly quickly at the speeds they are traveling, and are exposed to a total dosage of about 2 rem during each passage. From what we learned from Hiroshima, a total dosage of 20-50 rem is required to cause a noticeable increase in cancers, so 5 trips to the moon would put you at risk for cancer. BTW 500 rem or so will kill you outright, so staying in that band for a month or so _would_ kill you. Quote Share this post Link to post Share on other sites
