GCR has been known about since 1912, was measured by Apollo 16
www.lpi.usra.edu...
and the interaction between GCR and surface material was measured by Apollo 17 in the Lunar Neutron Probe Experiment.
You don't design experiments to measure something you don't know exists.
Then there are the famous 'light flashes' which were attributed to GCR.
Again, if you're saying you don't know how dangerous it was, or how much of it there was, then you can't say that it would have made the mission impossible. Tell us how you think this would have stopped the Apollo astronauts getting to the moon.

Your sweeping generalisation is hopelessly wrong and presumably has been plucked out of thin air.
If you read the article I just posted it refers to Apollo data. Apollo samples and data are still being analysed today and the results are easy to find.
And no spacecraft with a human crew will EVER be built of aluminum, for any deep space missions. None..
The CM will be built of the aluminium-lithium alloy used on the Space Shuttle external tank, and the Delta IV and Atlas V rockets.

As has been repeatedly pointed out to you:
Bremsstrahlung was well known and discussed prior to Apollo was considered during the design of it.
Aluminium was not the only material used in construction.
Apollo astronauts were not risk averse cowards ignorant of the dangers.
You have not yet identified which part of the radiation spectrum reached levels that would either incapacitate the Apollo crew or the equipment and thus render the missions impossible, or when this incapacitation would have occurred.
You have not ever presented one shred of evidence that proves your case. You have also conveniently skipped over the bit where you were proven wrong about the lack of knowledge about GCR or their measurement.

Except for the only one currently in production, of course:

en.wikipedia.org...(spacecraft)
Yes, the lithium helps to lower the "z," making it superior to pure aluminum. Nevertheless, improved technology does not make earlier technology "wrong."
Again, I'm not talking about Bremsstrahlung here.

No, they don't say anything is "negligible", for any duration in deep space, at all.
YOU are simply making things up, as usual...
They don't say it's possible, and that's the main problem here...
They said it was unsafe because there is data which proved it, based on their references noted in the paper...
What the?
It's not safe, that's the point..
They don't know exactly how unsafe - dangerous - deep space is to humans. That is what they are trying to find out, so we can one day go into deep space, with humans...
Yikes!
They said it is not safe, that's why I mentioned it to you, as THEY said it was not safe, in their paper...
THEY claimed it. I've pointed that out to you, over and over again, ad nauseum...
But now, trying to compare it to cigarettes, or LeBron James..... seriously??

GCR effects ARE unknown...
You ask me how they know it's a hazard to humans, but they don't know the effects of GCR on humans....
Knowing it as a hazard is based on their findings to date, which show it as hazardous to humans....
Now, look closely at what they are stating, in the paper....
They say aluminum may be more hazardous to humans than before, because aluminum actually intensifies the GCR radiation...
"May" be worse?
They didn't know if it was worse, at the time, it "may" be...
Why would they have believed aluminum "may" intensify GCR radiation, if Apollo had 'proved' the exact opposite? That aluminum was good for short-stay missions, at very least.
Apollo's dosimeters were (supposedly) able to measure all forms of radiation in space, as one 'accumulated dosage' of all radiation, over the whole mission...
Not knowing what specific types of radiation exist in deep space, Apollo measures all of the radiation, in one entire lump sum total of all radiation, over an entire mission!
All types of radiation are the same, and lumped together, as one heapin' pile o' radiation! Don't know about this or that type of radiation, and shore 'nuff, we's don't need to know it...seein' how they're all 'bout the same thingamajig, anyhoo!
Right, of course!
Look at how they approached the LEO environment, and compare it to how they approached the so-called 'moon landings'...
LEO was near, and studied for years, and we had animals, etc. test the environment, long before any manned missions went forth.
Beyond LEO, the environment is far more unknown, and hazardous. So manned missions are good to go, no need to test it with animals, or whatever...they just know it's perfectly safe to send humans right away!
Who buys such crap??
This is an alloy, with some aluminum mixed with lithium....and is not aluminum, like Apollo had.

so where exactly do they say they are not excluding Apollo???
YOU are simply making things up, as usual...
you will find that them not using Apollo data for GCR studys is because the dose received is negligible and so is the sample size.
They don't say it's possible, and that's the main problem here...
no thats your main problem with this..
you seem to think that if something is deemed UNSAFE it must mean that that activity cannot be done at all in any shape or form.
They said it was unsafe because there is data which proved it, based on their references noted in the paper...
there are many things that are unsafe.. such as skydiving, speeding, rock climbing, smoking cigarettes etc..
oh and what references in the paper?? as far as you are concerned all the data was fake to begin with..
What the?
you are basing your conclusions on the findings of a paper that is using fake made up data..
ie. the data being lebron james is a woman, and you reading an article about how lebron james is a woman.. therefore you have come to the conclusion that NBA is all fake..
It's not safe, that's the point..
They don't know exactly how unsafe - dangerous - deep space is to humans. That is what they are trying to find out, so we can one day go into deep space, with humans...
being unsafe doesnt make things impossible.. dont you get that??
speeding is unsafe, it is very possible to do..
smoking cigarettes is unsafe, also very possible to do..
visiting chernobyl is unsafe, also very possible to do..
cave diving is unsafe, also very possible to do..
get the idea yet?
Yikes!
They said it is not safe, that's why I mentioned it to you, as THEY said it was not safe, in their paper...
yes and cigarettes were deemed healthy when they were introduced.
THEY claimed it. I've pointed that out to you, over and over again, ad nauseum...
But now, trying to compare it to cigarettes, or LeBron James..... seriously??
yes i want you to justify how cigarettes were first sold and are still sold given their link to cancer.
they are unsafe, but i see people smoking daily..

The first point you still don't get is that they are not talking about any exclusions.
This does not have an exclusion of 'less dangerous' than long missions'..
In your world, if they don't specifically say 'Apollo missions are NOT excluded'...then they are excluded!!
NOT to exclude something is actually excluding it!?!?
They are required to state any exclusion,

To make it known that short missions are safe...
not being psychics like you are...
Future missions will not be built of aluminum ...
Testing a craft in LEO which is not even aluminum but rather an alloy
Apollo was aluminum, not an alloy..
Try again..

They are required to state any exclusion,
Please cite the rule which specifies this requirement.
Is it in the Lunar Landing Skeptic's Handbook?
They are scientists, any excusions must be known, so required to state...
