The problem is particles undergo a process called fragmentation
The study of cataract in astronauts is of interest largely because these workers are exposed to higher doses and different patterns of radiation than other more Earth-bound populations — and increased radiation exposure is linked to increased risk of cataract. The study included all 215 astronauts from the US astronaut program, and it includes those who have flown only in low-inclination (still partially in Earth's atmosphere) as well as those who have walked on the moon.

Stars again? Seriously?
Maybe you can explain just exactly what point that idiotic video is trying to make. I don't see one.
Armstrong said he didn't see stars. That makes sense, his eyes were adapted to the bright lunar surface. I thought this had all been covered before.

Seems a bit pointless studying astronauts who have been to the moon if they hadn't actually gone no? They would have had to volunteer to be exposed to radiation to keep up the story. I wouldn't volunteer for that.
COLLINS: Day 4 has a decidedly different feel to it. Instead of nine hours' sleep, I get seven -- and fitful ones at that. Despite our concentrated effort to conserve our energy on the way to the Moon, the pressure is overtaking us (or me at least), and I feel that all of us are aware that the honeymoon is over and we are about to lay our little pink bodies on the line. Our first shock comes as we stop our spinning motion and swing ourselves around so as to bring the Moon into view. We have not been able to see the Moon for nearly a day now, and the change is electrifying. The Moon I have known all my life, that two- dimensional small yellow disk in the sky, has gone away somewhere, to be replaced by the most awesome sphere I have ever seen. To begin with it is huge, completely filling our window. Second, it is three-dimensional. The belly of it bulges out toward us in such a pronounced fashion that I almost feel I can reach out and touch it. To add to the dramatic effect, we can see the stars again. We are in the shadow of the Moon now, and the elusive stars have reappeared.

Should I point it out again?
Apollo 11 0.18 rads 08 days (moon landing)
Apollo 8 0.16 rads 08 days (circling the moon)
Apollo 7 0.16 rads 10 days (LEO)
Gemini 7 0.16 rads 13 days (LEO)

It doesn't matter who claimed to have a reflector .. the mythbusters have been well . um .. been busted.
It seems anyone can bounce a beam off the moon and get a reading.
But now Tom Murphy from the University of California, San Diego, who leads one of the teams at the Apache Point Observatory in Sunspot, New Mexico, thinks the mirrors have become coated in moon dust. "The lunar reflectors are not as good as they used to be by a factor of 10," he says.
This is actual evidence that the very tools that scientists use routinely - monthly, are being damaged. You think they're making this up? funny.
He suspects that moon dust is either coating the surface of the mirrors or has scratched them.

So how did the Soviets get those mirrors on the moon if they claimed they never landed a man up there
You think the Soviets lied about landing people on the moon? You think the US&USSR have been busy colonizing the moon without us knowing about it?
Please explain!!!!
Using data collected by a NASA spacecraft, experts were finally able to rediscover a long-lost, Soviet-built reflecting device on the surface of the Moon. The exact location of the scientific payload has remained a mystery since September 14, 1971. At that date, the Soviet Union lost contact with its Lunokhod 1 rover, which was carrying the mirrors. Nearly 40 years later, American physicists were able to identify the instrument using lasers beamed to the Moon all the way from Earth, Space reports.
.....it landed on the natural satellite on November 17, 1970, aboard the lander segment of the Lunokhod 1 mission. The rover was then deployed, and began its trek across the lunar surface. Eventually, in September the following year, contact with the small exploration robot was lost, and its location became a mystery. “No one had seen the reflector since 1971,”

Should I point it out at all? South Atlantic Anomaly. The Gemini astronauts passed through it repeatedly. Other Apollo missions received higher doses. Background radiation exposure is always a crap shoot. The solar winds vary continuously and hard radiation from galactic cosmic rays is completely random.

It's really simple, the Soviets sent a robot and the Americans sent dudes......Is it really that hard to grasp?

According to you, all of the Apollo astronauts are liars.
I don't know about anything else they may have said, but they didn't lie about going to the Moon and back.

Explain how Collins could go around the dark side of the moon and not see stars.
00 09 19 09 CMP Also, I've been occasionally looking out to see if I could see stars at various sun angles and at this particular altitude, it's very difficult. In the scanning telescope the sun is very bright and the earth is very bright. And if I looked at the earth and try to look for stars, I lose my dark adaptation very quickly.
00 10 09 16 CDR Houston, this is Apollo 8. Be advised that we doubted that it would be possible to use the stars to get our backup alignment. We haven't been able to ate my stars through the scanning telescope yet.
03 13 50 22 LMP The sky up here is also rather forbidding, foreboding expanse of blackness, with no stars visible when we're flying over the moon in daylight

They were all military men. And would be likely to tell you and their wives
any story that their superiors told them to tell. Or you think soldiers always tell
the truth about their missions?
