Oh, really now, choos. Why were they carrying PRD's if they weren't collecting data off them?
It fits in with the von Braun disclosure because the American manned effort outside of Low Earth orbit was for propaganda and military purposes. That means there was an enemy, the Commies, who had to be defeated. During a state of war there is no planning to lose, one always plans to win. Since winning against the Reds was the only goal, manned flight outsideLEO was not essential for a victory... that's why everthing about Apollo was scripted and rehearsed and planned for a massive world-wide Television audience, which includes the third world countries, who being mostly illiterate and non-English speaking were easily impressed by the big rockets and puppet show.
Come on choos. You are not even trying to understand the American mindset of 1968-1972.
Who cares about recent studies except for you the Apollo Defenders??? The Apollo Investigators are asking for the Third time now asking for the empirical PRD data. If you don't have it just admit that NASA's radiation summary tables are based on engineering fantasies, medical fraud and sugar coated science data.
The military has always had a concurrent technology (or better) than what NASA has. So why didn't the Pentagon send a 1-man crew mission for a loop around the moon? (maybe they did?) It's trivial choos. TRIVIAL.
Yet no one can do it except NASA during Richard Nixon's presidency. Just one loop around the moon. That's all I would require to believe the space radiation claims made NASA in it's published orthodox compendiums.
Yet all you have here are the pedestrian and clearly unscientific NASA summary tables parcelled together with 'recent' psuedo-science masquerading as real science
There is a huge difference between simulating shielding in a lab using Monte Carlo techniques. It's just computer simulation. Compare that to the real science of actually sending a 1-man crew to orbit the moon. That's real. And it hasn't been done in 41 years, mate. Trivial.
Remember when I said earlier in the thread that during the early years of aviation every damned fool and his sister were lining up for the chance to make suicide run across the Atlantic? Well where are the suicide runners now? They can't get out of Earth orbit. Trivial in 1968.

Lord Rothermere..(owner of the Daily Mail) was a friend of Benito Mussolini and Adolf Hitler, and directed the Mail's editorial stance towards them in the 1930s.[32][33] Rothermere's 1933 leader "Youth Triumphant" praised the new Nazi regime's accomplishments, and was subsequently used as propaganda by them.[34] In it, Rothermere predicted that "The minor misdeeds of individual Nazis would be submerged by the immense benefits the new regime is already bestowing upon Germany". Journalist John Simpson, in a book on journalism, suggested that Rothermere was referring to the violence against Jews and Communists rather than the detention of political prisoners.[35]
Rothermere and the Mail were also editorially sympathetic to Oswald Mosley and the British Union of Fascists.[36] Rothermere wrote an article entitled "Hurrah for the Blackshirts" in January 1934, praising Mosley for his "sound, commonsense, Conservative doctrine".[37] This support ended after violence at a BUF rally in Kensington Olympia later that year.

choos, Are you even tryin? to search the internet? for 1 minute before you give up looking for the empirical Apollo PRD data? ? ?
So the individual Apollo empirical PRD readings do exist. Just tucked away in the transcripts... that are confirmed by the checklists. I wonder why NASA would make it so hard to find this data?
Do the PRD readings from Apollo transcripts confirm the conclusions made in this NASA summary table?

But the worst part about it is that you didn't even try. Is that how the real world works for you?
This is Michael Collins PRD. As you can see someone has written some readings on the unit.

this data is scientifically unimportant
In the 60s they just didnt have all the facts

well when background exposure rates of GCR's are around 150-200mGy PER YEAR.. so a background GCR rates of about 15-20cGy PER YEAR.. so for 12 days (short high profile missions) they would be exposed to about 0.66cGy.. which is 0.0066Gy.. its simply not enough to see the effects of GCR's. its very very difficult study that which you cannot see. especially when it comes to radiation..

Let's look at more recent figures..
The RAD data showed the Curiosity rover was exposed to an average of 1.8 milliSieverts of GCR per day on its journey to Mars,” NASA reported.
www.highlightpress.com...
1.8 mSv = 1.8 mGy.
1.8 mGy = 0.0018 Gy
0.0018 x 12 (days) = 0.0216 Gy
So it's more than 3x your figures.
Anyway, it doesn't matter what the figures are, because they'd be able to measure them regardless.
To claim "its simply not enough to see the effects of GCR's" makes no sense.
Not even an SPE was a problem, supposedly...
"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."
www.hq.nasa.gov...
They had sensprs outside the capsule, as well as inside it, Clearly, they'd have different readings. But they didn't find any at all. Which means they weren't in deep space.

These types of radiation are measured in Sieverts (Sv), and research has shown that exposure to SEPs and GCRs increases cancer risk. A dose of 1 Sv, according to NASA, increases a person’s cancer risk by 5 percent over their lifetime. At present, NASA limits an astronaut’s cancer risk to 3 percent, which is about 0.6 Sv, or 600 milliSieverts.

I thought you guys were supposed to be the ones with the strong science background. You know, using science to prove Apollo. But here you just denied the importance of empirical data which does not make sense at all.
and use of the sievert implies that appropriate weighting factors have been applied to the original absorbed dose measurement (in grays)

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.

so 1 Sv gives an increased risk of getting cancer by 5%.
as per your claim, a 12 day mission should have made them seriously sick and probably even killed all on board.. which would be much higher than 1 Sv.. maybe in the ball park of about 1+ sieverts per hour because we arent talking about an increased risk of getting cancer we are talking about maybe them seriously sick and maybe even death in less than 6 days as per your claim.
also can i point out this:
37.9cSv per year is 0.104cSv per day which is equal to 1.04 millisieverts per day.. and the mars missions 1.8 millisievert per day.. but the 37.9 is for a solar maximum not sure what the curiosity was, so there will be some discrepancy especially since the 1977 solar minimum was 120 cSv per year. which is 3.3 millisievert per day.
but good effort, atleast you are trying to find answers now instead of making things up.edit on 12-7-2013 by choos because: (no reason given)edit on 12-7-2013 by choos because: (no reason given)

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.
