"allowable exposures for this high-risk mission"
It is a speculative paper, showing the allowable exposures for radiation. It does NOT say those were the doses of radiation suffered by the astronauts. It says those numbers are exposure limits, in case of a possible solar event. Which didn't happen!
The recorded amount of radiation suffered by the astronauts was MUCH less, this is a documented fact.
Look more closely at your sources!

U.S. Average Exposure
Source Exposure in mrem/yr
Cosmic rays 45
External radiation from
radioactive ores, etc. 60
Internal exposure from
radioactive material
ingested into the body 25
Diagnostic X-rays 70
Total: 200

More to the point. The average US citizen is exposed to 200 mRems a yeaf

Just for kicks, I asked one of our radiologists at work what the average exposure per year is for them and it corelates well with the source listed above. He said about 400-500 mrems a year. Most of out tech are waling around with no problems. So a 500 mrem exposure on a lunar mission is well withing a tolerable level.

The fact is it was calculated in "REM" and not in "MREM"
if you ceck my last 2 posts you will see what i am talking about.

And you haven't been reading my posts, Keen's posts, and Half's posts, and everyone else's. It's all about length of exposure. Sure the moon is highly radioactive, but just because it is doesn't mean it's dangerous. If you understood how radiation affects us, you'd know that the danger is proportionate to time. They weren't on the moon long, not long at all. I agree that several days or weeks constantly on the moon could have caused them serious health issues, perhaps death. But they weren't there that long at all.

Why argue with simple facts?
Go study the moon it's self first than make wild statements

500 mrems was the maximum exposure. I like many before me fail to understand what exactly you are arguing here if you are going to first cite then ignore your own sources

Because I know that damage from radiation takes time. Simple concept dumbed down for you: put a raw chicken into an oven, at 350 degrees.

Radiation especialy gamma rays can have a impact in a short period of time

You can start here.

You can read difrent articles about the moon than form a opinion.
I can not give you all the book marks simply cause i didint book mark them.
But there is plenty of that you can find it.

Just think if we get a few rems just for flyng on a plane what would the impact of a radioactive surface be?
