I am going to have to study up on the secondary radiation effects she mentions, specifically neutron radiation.
It doesn't sound good though.
Thomas Dolan.... was an American engineer who proposed the first fully-developed concept of Lunar orbit rendezvous for the Apollo program while working at Vought Astronautics.
Dolan referred to his LOR study concept, Manned Lunar Landing and Return (MALLR) was largely ignored by NASA administrators until Langley engineer John Houbolt began championing the concept in 1961.
Radiation Ruination To Be Avoided On Chandrayaan-II, Says ISRO
The intense radiation from the sun that roasted India's first unmanned lunar satellite's key orientation instrument — the star sensor — has raised concerns over the safety of Indian astronauts on the country's first manned space flight, planned around 2015.
Scientists plan to land a robotic rover that will explore the lunar surface in their Chandrayaan-II mission. They are now awaiting the conclusion of ISRO's review meeting to take stock of the Chandrayaan-I mission, including the failure of the star sensors, which will be held later this year. Annadurai admitted that as this was the first time that India had sent a satellite into a close lunar orbit at an altitude of just 100 kms, "we have learned from our experience that we need to improve the radiation shield for the next mission."
At a distance of just 100km from the Moon's surface, any lunar satellite receives an overdose of radiation, primarily the direct blasts from the sun, and secondarily, the reflected radiation off the moon's surface. One of the avenues space scientists must deal with regarding high radiation threats to satellites is to completely close down the satellite's operations. "But we cannot close down the star sensor as that would mean losing the orientation of the satellite, which is difficult to regain later," said Annadurai. The star sensors keep the satellite pointed in a particular direction. This is a key instrument for satellites that can help the camera side pointed at the earth's or moon's surface.

ISRO, NASA joint test with Chandrayaan-1 had failed news 09 September 2009
The premature shut-down of the Indian Space Research Organisation's Chandrayaan-1 lunar mission on 29 August also brought to a close an interesting joint effort with NASA's Lunar Reconnaissance Orbiter (LRO) where both agencies were deploying US-provided synthetic aperture radars for bi-static observations aimed at finding water ice at the moon's poles.
The experiment intended to make use of the proximity of both spacecraft to each other in their separate orbits around the moon to look down into a deep crater from slightly different angles so as to confirm the presence of ice at its bottom.
The tricky bistatic manoeuvre was carried out on 20 August over the Erlanger Crater near the moon's North Pole. It was timed to coincide with a moment when both spacecraft were only 20 kilometers (12.4 miles) apart.
ISRO should be congratulated," Nozette said. "They did a good job, but the moon is somewhat of a harsh environment." Source www.domain-b.com...
After suffering from several technical issues including failure of the star sensors and poor thermal shielding, Chandrayaan stopped sending radio signals at 1:30 AM IST on 29 August 2009 shortly after which, the ISRO officially declared the mission over. Source Wikipedia

Scientist Rubbishes Apollo 15 Conspiracy Theory
by Staff Writers
Delhi, India (PTI) Sep 04, 2009
The Terrain mapper camera (TMC) on board Chandrayaan-1, which had an abrupt end a few days back, has sent the prints of landing site of Apollo 15 and tracks of the lunar rovers used by astronauts to travel on lunar surface, a senior scientist associated with India's lunar mission said during a presentation here.
"The images captured by hyper spectral camera fitted as a part of Chandrayaan-1 image payload has reconfirmed the veracity of Apollo 15 mission," said Dr. Prakash Chauhan, who is a senior scientist with Indian Space Research Organisation's (ISRO) Hyderabad-based space application centre.
ISRO Seeks To Allay Concern Over Security

Bangalore, India (PTI) Oct 22, 2009
Indian Space Research Organisation has said that the arrest of a senior American scientist, who played a key role in the Chandrayaan-1 moon mission, was "no reason for concern" as it had followed all security protocols.
The scientist, Stewart David Nozette who has been arrested for alleged espionage in the US, had no access to any "critical" Indian document, ISRO chief spokesperson S Satish said.
"All security protocols had been followed," he said adding, any foreign scientist visiting ISRO had to have all the necessary clearance and submit all valid documents.
Nozette's visits were restricted to the Mini-Sar, an American scientific instrument that flew on board Chandrayaan spacecraft, he said. National Aeronautics and Space Administration had two instruments on Chandrayaan odyssey.
The US Federal Bureau of Investigation on Monday had filed a criminal complaint against Nozette on charge of spying for Israeli intelligence.

Radiation was not an operational problem during the Apollo Program. Doses received by the crewmen of Apollo missions 7 through 17 were small because no major solar-particle events occurred during those missions. 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. Solar-particle releases are random events, and it is possible that flares, with the accompanying energetic nuclear particles, might hinder future flights beyond the magnetosphere of the Earth.

To refresh you're rather poor memory, this is the graph of MARIE data taken in orbit around Mars which has virtually no magnetosphere and therefore offers virtually no protection:
The largest peak will be the X3 class flare that occurred on the 20th July 2002:
www.spaceweather.com...
It reached 2866 mrad / day which equates to only 0.02866 Gy / Day. Hardly an issue when it's short term exposure.
You keep being told, hopefully it will sink in one day, the problem with radiation in space is long term exposure. Read it in your head, then repeat it out loud Foos: the problem with radiation in space is long term exposure. Keep doing this until it sinks in.
Ironically, in the Autumn of 2003 after a series of particularly strong solar flares MARIE started malfunctioning, probably as a result of being exposed to the solar flare's intense blast of particle radiation. The instrument was never restored to working order.
The MARIE problem occurred less than 4 hours after the onset of a huge solar particle
event (SPE) which began near 11:00 UT on day 301. Figure 1 shows GOES11 proton
fluxes for this time period, and the continuation of high fluxes into early November. On
day 301, Odyssey lacked DSN coverage from about 11:00 to 16:00 UT, and when
coverage was restored, the DC-DC converter temperature problem was noticed
immediately. It is impossible, to determine the exact time at which the problem started,
but indications of high temperature began at about 14:30 UT. The day 301 SPE was the
second major eruption within 48 hours. The earlier event began about 18:00 UT on day
299 and MARIE successfully recorded most of it. This event did not fully subsided when
the subsequent second event occurred.
Prior to the day 299 SPE, the average measured dose rate was 22.5 ± 4 mrad/day as
measured by the A1 counter and 22.6 ± 4 mrad/day as measured by A1-A2 coincidence
data. The uncertainties in the dose rates reflect the present state of our understanding of
the instrument properties (geometry factor, trigger threshold, etc.) that go into the
normalization factors used to convert count rate to dose rate. The science team continues
working to understand and reduce these uncertainties.

So all you have proven is the design of the MARIE experiment in protecting it from the radiation was flawed, nothing more.
Chandrayaan-I also suffered the same fate. At an unlikely time. When other satellites owned by NASA are operating and functioning normally several other satellites owned by foreign countries are getting knocked out by lasers when they get too close to the *very sensitive* Apollo landing sites. It is therefore NASA's top priority to control every piece of historical data, every single byte of data, with regard to moon data.
NASA ESPIONAGE on Chandraayan-I
The bigger secret is the Air Force's nuclear pulsed engined Aurora which did go to the moon...but everyone DIED from that first little mis-adventure. If the public knew about that they would have demanded no further space exploration. Gotta break a few eggs to make an omelette...so those poor guys died and never even made it to the history books to be remembered.
Many of our guys in the nuclear field all die within 20-25 years due to what they've been doing. We go to great lengths to protect those little dirty facts.
Operating for 33 years, 3 months, and 24 days, the spacecraft receives routine commands and transmits data back to the Deep Space Network. Currently in extended mission, the spacecraft is tasked with locating and studying the boundaries of the Solar System, including the Kuiper belt, the heliosphere and interstellar space. The primary mission ended November 20th, 1980 after encountering the Jovian system in 1979 and the Saturnian system in 1980.en.wikipedia.org...
After the completion of all the major mission objectives, the orbit of Chandrayaan-1 spacecraft, which was at a height of 100 km from the lunar surface since November 2008, had to be raised to 200 km due to malfunctions.
After suffering from several technical issues including failure of the star sensors and poor thermal shielding....
Rise of spacecraft's temperature
ISRO had reported on 25 November 2008 that Chandrayaan-1's temperature had risen above normal to 50°C, scientists said that it was caused by higher than normal temperatures in lunar orbit.
The temperature was brought down by about 10°C by rotating the spacecraft about 20 degrees and switching off some of the instruments.
(skip)
The spacecraft was experiencing high temperature because of radiation from the Sun and infrared radiation reflected by the Moon.
Well 11 flights with no radiation problems but your guy says radiation may effect future flights..
How lucky were they with the Apollo missions since, at the time, they knew so little about the sun's effects..?
Kill astronauts? I hope not. I don't even want to think about that.
Jarrah discussed not only the Apollo moon hoax but also suggested that the Challenger explosion could have been orchestrated by the government to cover-up knowledge Christa McAuliffe might reveal to the public."
The NASA testimony (Frank Borman) about Apollo 1 and the oxygen environment makes me a bit nauseated

There's going to be no retraction Foos and here's why:
I added the MARIE data about 10-15 minutes after making my initial post, you replied about 3 hours and 20 minutes later so it was already there when you responded.
