It doesn't matter the dummy won't survive the Van Allen belt LL ~. But here is a serious question. If the Van Allen belt has such high radiation how did the Apollo astronauts survive it in 1969 flying in a beer can?
Multiple reasons - they blew through it in a few minutes, and the "tin can" easily blocks most ionizing radiation. It does less well against gamma radiation but it may have cut the gamma flux by a factor of two or more. I saw the analysis somewhere, but it has been a while, so don't place any wagers on my recollection.
The total dose for each astronaut was read out at least twice a day throughout the missions, and more for Apollo 8 (the first time through) and the total dose for the entire mission was negligible to very low and not medically relevant. As I recall, the dose from just the Van Allen belts was below one count on the dosimeters, again, you can read the entire air/ground transcript and onboard voice recorder transcript and get the relative doses at various points, or dig around and find the flight surgeons report where they have a plot of total dose over the missions.
The "fake moon landing" nuts use the radiation as "proof" that it couldn't have been done. The reason that anyone pays any attention even a little bit is that the general public has an *insanely overblown and histrionic" idea of the actual danger of radiation exposure. One click of the Gieger counter and "we are all going to DIE!!!"
Marie Curie spent most of her professional life discovering and then working with (and carrying around in her pockets) one of the most powerful radioactive elements, Radium. Yes, she died of radiation exposure and they buried her in a lead coffin. But, as it turns out, the radiation she died from was not ionizng radiation from Radium or other radioactive elements - it was X-Rays from the unshielded X-ray machine she used as a volunteer in World War I. There have been accidents that resulted in people getting acute radiation sickness at very high doses, getting over it, and living with it until they died of a heart attack at 80. The very small doses we are talking about here have never been proven to be detrimental in any way.
Of all the places in the world you might be worried about, you would think it would be Hiroshima and Nagasaki, Hiroshima in particular being caked with unreacted enriched uranium, since only about 2% of the nuclear materials in the bomb were actually consumed in the reaction before it disassembled itself. So, nuclear wasteland? No, my minivan was made there, that's where the Mazda factory is. Chernobyl was even dirtier, and everyone has been evacuated for decades. It has turned into a nature preserve, despite the fact that you catch, say, a rabbit, and it's clearly full of radioactive plant leaves.
The Apollo astronauts generally lived to ripe old ages, dying from the usual old man causes from the era of smoking and steak for breakfast. The few exceptions, particularly Jim Irwin, were almost certainly caused by something else, in the case of Irwin, severe potassium deficiency that built up due to dehydration during his Apollo 15 spacewalks. They were concerned by he and Scott (to a much lesser degree) developed abnormal heart rhythms, as they had an extended and very strenuous EVAs, particularly, trying to extract the core sample that got stuck. The flight surgeon said that he was on the ground, they would have had Irwin in the ICU after the first EVA. Of course, the capsule was pure oxygen and they made him wear the heart monitor leads for the rest of the mission, so it wasn't too far off from an ICU anyway. This led to an ridiculous overreaction by adding potassium to everything they took on 16, particularly the orange juice, which resulted in extreme flatulence and diarrhea - which is not something you want to spend 10 days in a closed capsule with. On 16, when the frogmen opened the door, they slammed it back shut again, because the smell was so bad. This, too was captured in the on-board voice, you can read the transcript if you want...
The most serious radiation problem facing astronauts is X-rays from a solar flare. That really will go through conventional spacecraft materials like aluminum like sh*t through a goose, and the doses can be critical. Had there been a Class M or X solar flare during an Apollo mission, it could easily have been fatal. They paid a little bit of attention to sunspots at the time, and had there been an obvious threat they might have postponed the mission. It was a near miss on (again) 15, I think there was a flare right after they got back. Otherwise, statistics will tell you the threat, it's the likelihood of a sufficiently large flare during any particular 10 day period, aimed your way, you take your chances. For a year-and-a-half Mars mission, you absolutely have to deal with this somehow because it's likely to happen. It's a soluble problem, build a tantalum or lead shield, or use the water you are taking as a shield (A LOT of thickness of water is required, like a giant tank the long way through), aim it in the right direction, and shelter under it for a few minutes/hours.
Most of what the public knows, or thinks it knows, about radiation is complete nonsense, and its by hyped to the stars by people wanting to cause people to be unreasonably frightened of it for reasons of politics/manipulation.

p.s. Apollo 15 radiation exposure was 360 millirads for Scott and 510 millirads for Irwn (.36 and .51 rads). That's about a year's worth of exposure on the ground from natural sources. Scott's personal dosimeter failed and he took Worden's since he was going outside, so no personal reading for Al. The passive dosimeters (I think it was a film badge) were about 300 millirads. Here is a table from a source that I consider somewhat alarmist, but:
25 rad: lowest dose that causes observable blood changes
200 rad: local dose for onset of skin redness in humans
400 rad: predicted 50% chance of acute radiation sickness
1000 rad: predicted 100% chance of acute radiation sickness
So, the exposure was around 1/50th of what it takes to cause detectable effects
p. p. s. Average Radiation Doses of the Flight Crews for the Apollo Missions
Apollo Mission
Skin Dose, rads
7 0.16 < low earth orbit below belts
8 0.16 < lunar orbit and through the belts
9 0.20 < low earth orbit below belts
10 0.48 < lunar orbit and through the belts
11 0.18 < lunar orbit, landing and through the belts
12 0.58 < lunar orbit, landing and through the belts
13 0.24 < lunar free-return loop and through the belts
14 1.14 < lunar orbit, landing and through the belts
15 0.30 < lunar orbit, landing and through the belts
16 0.51 < lunar orbit, landing and through the belts
17 0.55 < lunar orbit, landing and through the belts
So it seems the exposure through the belts was much lower than the flight-to-flight variation - 7 and 8 were the same
