SUMMARY: When humans return to the Moon in the next decade, they'll be facing a dangerous combination of cosmic rays and solar flares. Astronauts will need to avoid getting too much radiation, so NASA is working to better understand risks. The upcoming Lunar Reconnaissance Orbiter (LRO) will carefully measure and map the Moon's radiation environment. It will also have a special instrument designed to simulate how this radiation will affect the human body.

This sounds suspiciously like the conspiracy theorists argument that NASA didn't really understand the nature or extent of the radiation problem during the period of the Apollo missions.

If, as this article alludes they still don't know even today, how did NASA know in '69 the level of exposure and the subsequent impact on astronauts.

I am convinced personally we did indeed go to the moon, but articles like this get my conspiracy friends all fired up.

Specific to the issue of radiation, can anyone direct me where I might find definitive info so as to disuade those non believers.

Fred, http://www.clavius.org covers the above beautifully. There's a primer on radiation here (http://www.clavius.org/envradintro.html), which continues into the particulars (refutations of conspiracists' claims included).

Beat me to it, Wolverine! I was going to suggest the same thing.

Exposure time is the key issue. They knew roughly how much radiation the astronauts would be exposed to. The issue here is if you want to go to the moon for an extended stay, you want to know in detail what you are going to face, so you can prepare for it specifically, and keep the long term exposure to something reasonable.

There are both good and bad points on being on the lunar surface - you get more secondaries than in orbit, but you also can build a shelter and cover it with loose regolith for radiaiton protection.

Thanks to both Woverine and Van Rijn I will study up on the sites you mentioned. I have successfully refuted most of the conspiracy arguments through alot of research (the parallel shadows and waiving flag and footprints and many others)but this last issue is a bit more thorny - look forward to reading up on the subject
