If ON LOW-ORBIT radiattion is enogh to damage spacecraft. Then think what it can do with human body.
Also I ask few of my friends about this metal that can protect from radiation. It is lead. Only this metal was know in 60s that can protect from
radiation. To stand enogh radiation that is on moon you will need at least 15cm walls. but lead is too heavy, SO DID USA GO TO MOON????
"If ON LOW-ORBIT radiattion is enogh to damage spacecraft. Then think what it can do with human body. "
This article is talking about longer term damage than the astronauts were exposed to. Radiation "damage" (unless you are talking about MASSIVE
radiation exposure) is usually cumulative. Even flight personel exposed to over 27,000 hours of higher radiation levels only exhibit a 1% increase in
cancer rates. Smoking is more dangerous than this.
Next, you must understand, as stated above by another poster, that this satelite damage is "as a result of the Earth's magnetic field weakening
above our part of the planet. "
This was not happening to any appreciable effect back in 1969, and so is irrelevant.
"Also I ask few of my friends about this metal that can protect from radiation. It is lead. Only this metal was know in 60s that can protect from

Your friends dont know what they are talking about.
First of all GOLD will block this type of radiation (at a certain thickness), so your friends telling you that LEAD was the only known substance is
ridiculous. Im not saying that gold was used, Im just using it as an example of how your friends are speaking in ignorance.
Secondly it doesnt take 15 cm of lead to block Cosmic Radiation.
Thirdly, if you are talking about the Van Allen Belt, you need to read a bit more about the effects of radiation on the human body. The effects of
radiation arent *all at once* (unless you are talking about MASSIVE amounts, which the VAB dont have in the amounts you are speaking of). The adverse
effects of radiation are usually cumulative. The astronauts were only within the VAB for only about an hour. You will do more carcinomic (sp?)
damage to yourself by smoking a few cigarettes.
Read this link and you will understand the effects of the Van Allen Belts on the astronauts (or rather the lack of effects)-
