At least 39 former astronauts have suffered some form of cataracts after flying in space, according to a 2001 study by Francis Cucinotta of NASA's Johnson Space Center (see journal references below). Of those 39 astronauts, 36 had flown on high-radiation missions such as the Apollo Moon landings. Some cataracts appeared as soon as 4 or 5 years after the mission, but others took 10 or more years to manifest.

since you speak with so much conviction.. in order for you to prove your point you need to prove to me you understand the problem.
so ill ask again:
how long will it take for a person (male) to receive 1Sv dosage from exposures to GCR's?
until you can answer this simple question your argument cannot move forward.
failure to provide an answer proves you do not understand the problem.

Actually, you do not understand the problem...
We don't know the effects of GCR radiation exposure beyond LEO, nor how to shield humans in that environment.
Well, only 24 humans have gone beyond LEO, on the Apollo missions....short amount of time, so let's all move right along now, folks!
The data is ignored, same as all of it is, not a word...
Only 24 human beings have ventured beyond this protective envelope, and then, only for a maximum of approximately 12 days (Apollo 17). This represents a vanishingly short amount of time that humans have spent in the interplanetary radiation medium, certainly relative to the multi-year timeframe for a mission to the Mars.
Apollo is nothing more than a trivial footnote, at best... as I've told you, over and over again...
Excuses don't work.
They are saying that aluminum shielding, 40-50g/cm2 thickness, would protect humans against GCR radiation for one year, within deep space.....right? Is it their claim, or not? You think it is their claim, as you cite it for your argument. If so, then explain why they say aluminum is a poor shielding material within deep space, and may even intensifies the hazard, therefore, no future craft will be built with aluminum shielding?

While thicker shielding could in theory provide more protection, deploying a sufficient mass of shielding into space is limited by the practical capabilities of current spacecraft launch systems.
Space radiation is the number one risk to astronaut health on extended space exploration missions beyond the Earth’s magnetosphere. Only 24 human beings have ventured beyond this protective envelope, and then, only for a maximum of approximately 12 days (Apollo 17). This represents a vanishingly short amount of time that humans have spent in the interplanetary radiation medium, certainly relative to the multi-year timeframe for a mission to the Mars.
The acceptable levels of risk for space exploration beyond LEO have not been defined at this time and need to be dealt with before sending manned missions to colonize the moon or to deep space, such as a mission to Mars

You haven't actually quoted anyone that says what you claim they said, or provided the answer to the questions I've asked you repeatedly.
Surely you have the information to hand, seeing as you seem so convinced by it? In which case why not provide it?

so you are saying it COULD be dangerous?? since we dont know the effects??
do you know what IS dangerous and IS linked to cancer but people still do it everyday?? smoking.
are cigarettes a hoax??

The data is ignored, same as all of it is, not a word...
once again before you go on this tirade,
how long does it take for a person to accumulate 1Sv dosage of GCR's in deep space??
and a direct quote from your article:

hey you remember when you said this:
They are saying that aluminum shielding, 40-50g/cm2 thickness, would protect humans against GCR radiation for one year, within deep space.....right? Is it their claim, or not? You think it is their claim, as you cite it for your argument.

heres a snippet from your own article you just posted:
While thicker shielding could in theory provide more protection, deploying a sufficient mass of shielding into space is limited by the practical capabilities of current spacecraft launch systems.
i bet you still dont get it.. so you better go take your own advice, excuses wont work.
also i better highlight a part of the conclusion you quoted also since it flies straight against your argument

so basically your whole argument that short missions are not exlcuded is directly dealt with in your own article you posted. and it just so happens to be what everyone has been telling you.
still going to hold onto your excuse that whatever missions so and so are not excluded?

The whole problem is that every paper has to imply Apollo was genuine, knowing it was not ..
That's why they talk about missions to Mars, or long-term missions, and not short missions, like Apollo's...it is taboo...

They don't exclude ANY missions!
You assume they are excluding Apollo missions, when in fact, nothing at all was ever excluded...

If they actually have excluded Apollo missions, what reason(s) are given for excluding those missions, in the document?

No exclusions are mentioned, or even implied. And, no reason(s) are given, if they somehow HAD meant it as an exclusion!!
An exclusion is defined clearly in any scientific paper, it is an absolute requirement, in fact....
You've assumed they are excluding something without saying it, and this is just wishful thinking, on your part!
They don't even talk about the only data we have from ACTUAL deep space manned missions, right? You seriously think that would happen, because the missions were short, so they now have no use for any of the Apollo data, since they are planning on only long missions now, for future missions are all to be long missions, as we know!!

24 humans on short missions in deep space is no comparison to years-long missions, and that's why Apollo's data is worthless to the experts!!
But data from LEO, and unmanned probes, we can extrapolate for deep space data, as a guesstimate of the actual data, which is not Apollo's actual data, which is worthless to use, because the missions were short, as we know!!
Amazing logic, for sure...
The GCR fluence rate and spectrum outside of LEO have been generally characterized through measurements made by unmanned spacecraft, such as the Mars Science Laboratory (MSL) spacecraft that, over the period December 2011 through July 2012, carried the Mars Curiosity rover to the red planet
I asked Baysinger whether he found anything that NASA edited out – comments about things going wrong, the astronauts being loose with their language, or exclamations about meeting aliens! He said no – absolutely everything was transmitted to the public on TV. In fact he said, “that was kind of disappointing”. Part of the idea of this project was to hear the unedited “real story”, and it turned out there was nothing edited out.[iv] Indeed, Rutherford’s story (click here for hi-resolution version which you can read) makes no mention of hearing anything unusual.
Dr Paul Bennewitz, an electronics specialist, electronically intercepted radio and video frequencies that appeared to be extensive communications between piloted ships and ground controllers, although subsequent evidence exposed that the Air Force Office of Special Investigations had been feeding him hoaxed transmissions associated with a disinformation campaign.

apparently a portion of amateur radio operators are excessively enthusiastic and consider whatever they hear legitimate...
He then began intercepting radio and video transmissions that he believed were used by the UFOs and involved different ET races. He traced these transmissions to a base located under the Archuletta Mesa, near Dulce.
Do you have any evidence that Baysinger was specifically targeted by anyone, or why?
