It doesn't matter if it's six times higher or not, it's still well within limits that the human body can take. NASA has imposed stricter limits since the 1990s, and what Apollo was exposed to still falls way below those limits. Using the mGy figure of 1.8 mGy a day, on a 12 day mission, they were exposed to 21.6 mGy on average. The new NASA figures, from the 1990s, allow for 1000 mGy for the eye lens, 1500 mGy for skin, 250 mGy for BFO, 250 mGy for the heart, and 500 mGy for the CNS, in a 30 day period. They weren't even remotely close to the stricter limits imposed by NASA for more modern missions.
Even other space agencies have a much higher exposure limit than the Apollo astronauts would have been exposed to.
That's not relevant to my point.
Look...
Apollo craft took readings of radiation in deep space, right?
These readings were taken from both outside the craft, as well as inside the craft, right?
The craft was primarily aluminum, right?
Aluminum increases the hazard of deep space radiation, right?
What did we find with the Apollo readings, then?
They found no increased hazard within their aluminum craft, right?
Why not?
Because they were too small?
No.
The radiation is altered by aluminum fragmenting its particles. Small indeed!
But if you have sources to support your case, let's see it...

This is because you dont understand there are different types of radiation. basically 5 types astronauts are concerned with they are alpha particles beta particles gamma and x rays and finally neutrons. So aluminum easily stops alpha and beta particles so there not an issue. now we have gamma and x rays well apollo walls were not just aluminum let me explain.First the command module actually had 2 structures bonded together.The inner one consisted of a sheet of aluminum then honeycombed aluminum and then a bonded face sheet. Now this was done for thermal protection but the funny part is it helped alot against radiation as well.
Then we have the heat shielding. this started with fiberglass then a brazened steel honeycomb layer. then at least two inches of phenolic epoxy basically a type of plastic designed to burn off on reentry. So now that i went thru that back to gamma and x rays x rays can be stopped by glass. Oh wait there was glass in the walls we call it fiber glass and plastic so 3 of the 5 down. Now for the last two gamma and neutrinos. Gamma is dangerous especially if it and aluminum isnt much protection but wait as i pointed out there was more to the command module wasnt there. Granted not enough to stop them but enough not to make it worse either. And finally neutrinos nothing all all can stop them this is why the astronauts were seeing flashes of light that they kept reporting. they were registering as they passed thru them.
So now why do you know why the radiation might register higher on the outside of the craft since alot of the radiation would indeed be blocked? Loog the basic problem is gamma rays on a short mission even though they penetrated the hull its not going to hurt them in such a short exposure. However put them in the craft for a 2 yr mission to mars and its a whole different ball game.Odds are they would go thru a couple of gamma ray bursts wont kill them at least not right away but will all but guarantee they die of cancer.

It's not more dangerous than no shield as much as you wasn't it to be. It's not as effective but no matter how many times you say it, it's not as bad as no shield. Even the experts you misquote don't say that.

Ill be short, you have to look it up yourself or I'll do it later, but solar protons are shielded effectively by aluminium.
Solar protons do not penetrate aluminum like gcr.
Sorry no time you need to look it up yourself.
How is this relevant to my point?
Who said solar protons? Not me.
GCR's were mentioned, you do know that?
Radiation was not an operational problem during the Apollo Program. Doses
received by the crewmen of Apollo missions 7 to 15 were small because no major
solar -particle events occurred during those missions. One small event was detected
by a radiation sensor outside the Apollo 12 spacecraft, but no increase in radiation dose
to the crewmen inside the spacecraft was detected. Solar -particle releases are random
events, and it is possible that a flare, with the accompanying energetic nuclear parti-
cles, may hinder future flights beyond the magnetosphere.

Now, if you can show the sources I asked you for....

yes we were talking about GCR's and you used a quote refering to SPE's to prove a point about how sensors outside the craft registered a small event and inside didnt..
so how does that make sense?? using a small SPE to prove something about GCR's?edit on 13-7-2013 by choos because: (no reason given)

The point was to show that sensors were on the outside and inside, that's all.
You know the issue is related to GCR's, so why not stick to this point?

When I first began looking into the increasingly vexing problem of irreproducible scientific research I assumed that the bulk of the problem was caused by sloppy science. Not so, says a National Academy of Sciences study that attributes two thirds of the retractions in the biomedical and life-sciences to scientific misconduct. And remember, these are only the people that have gotten caught. source www.forbes.com...
How many graduate students are likely to turn in their Principal Investigator (PI) knowing that this would dash their hopes of earning a Ph.D.? How many post-docs would do the same, throwing away their chance for a faculty appointment? How many assistant professors would risk receiving tenure by outing a colleague? And how many PIs would be willing to wade into a controversy by bringing charges against the very same peers who review their publications and grant proposals?

You really should learn about what you are talking about before you spout off on things you don't understand.

Look this is easy the command module wasnt just a sheet of aluminum so saying aluminum makes it worse there fore its impossible is stupid. My first suggestion for people who believe this why dont you take the time to look up how the craft was built.Here ill even help heres a good starting point.
