So perhaps you could dig out the data from EACH of the Apollo missions that allegedly went to Moon that concur- i.e. How much did the radiation levels increase up to a level of 300 miles, what where the levels like up to 600 miles, and what happened to the dosimeters once the 600 miles was reached, FOR THE JOURNEY OUT, AND THE RETURN. PLEASE. This was men they were sending through the belts. Not a chunk of machinery.
Apparently Dr Van Allen seemed to think there was no problem travelling through the belts with the time the Apollo missions spent so no doubt there MUST be documentation to back this claim up because THEY ALREADY KNEW TEN YEARS BEFORE APOLLO ABOUT THE INCREASE IN RADIATION LEVELS IN THE BELTS SO THEY SHOULD HAVE BEEN CHECKING.
I think still you're missing the operative terminology here.
Dr. van Allen knew what the rate of energy in the belts were at various places. He also was well aware that the dose of radiation was dependent on the
time of exposure (sort of like how wet you'll get depends on how much time you're expose to a water stream), and fully realized that an adequately shielded vehicle, like thew Apollo CM, with a short exposure time, would, not, and of course didn't produce anything close to a harmful dose of radiation.
As to you question, it should be noted that we measured cumulative dose, not rate of particle flow.
You see, a geiger counter or similar device is used to measure the radiation level at a given place. Think of a stream of water.
If you wish to find out how much water is flowing, you place a metering device in it that will measure the rate of flow in some applicable unit...like ounces per minute or gallons per hour. This is akin to what a radiation meter like a GM tube does.
Now, if you want to measure a given quantity, not a rate, but a quantity, you put a bucket under the water stream for a given amount of time and collect the water. Then you can see how much the "dose" of water is...entirely dependent upon the
time of exposure. That's what we measured in Apollo, because only that was significant from a biomedical standpoint. We used things called dosimeters for the purpose.
We didn't collect rate data on radiation flux, we collected
cumulative dose of radiation (essentially, we stuck the bucket under the radiation faucet for the amount of time we were in it, and collected the dose).
Now, all of the Apollo mission reports contain discussions of cumulative radiation
dosages measured by the various dosimeters carried on the crewsmen's persons and in the spacecraft at various locations.
There was a van Allen dosimeter on board, and it recorded the following data (in rads...a largely obsolete data point anymore, replaced by the gray which is 100 rads).
For Apollo 11, 0.11 rad skin dose, and 0.08 rad for tissue depth...for the entire mission.
On Apollo 12, 0.97 rad skin dose, and 0.51 rad for depth...for the entire mission.
...based upon what I told you about dose above, you might conclude that Apollo 12 spent more time in the belts. They did indeed, as their trajectory for entry put them through the belts for a longer period.Now, this rad business is rather meaningless unless it's put into perspective. What's it mean, relative to something actually dangerous?
A lethal dose of such radiation would be in the area of 160 rad/yr.
The Apollo radiation dosages were higher than normal exposure on Earth to background radiation, but much lower than a permissible exposure limit for persons working with radioactive materials, and in the case of Apollo 11, on average, about 7/100 % a lethal dose (1/1400 a lethal dose), Apollo 12 about 6/10 % lethal dosage (about 1/165th a lethal dose).
In both cases, virtually insignificant radiation exposures.
I refer you to the
Apollo Mission Reports,
The Biomedical Results of Apollo (NASA-SP-368, 1975),
Radiation Dosimetry for Manned Spaceflight in... Protection Against Space Radiation (NASA SP-169, 1967).
The topic was understood long ago, the data supported the understandings based upon spacecraft insulation design (which had nothing to do with lead and alot more to do with plastic...which makes perfect sense if you understand the type of particle radiation we were shielding against), and exposure times (
you don't get real wet if you run through the sprinkler real fast).
Radiation was not an operational problem for Apollo.

I have already told you Jodrell Bank COULDN'T track Apollo because THEY WERE NOT GIVEN THE DATA BY NASA TO POINT THE 250 FT DISH. Jodrell Bank claim they listened in to the radio transmissions on the 50 ft dish. Nobody has been able to validate why Jodrell Bank were tracking Luna 15 and WHO requested it.
Jodrell Bank have a neat little graph showing the Apollo 11 LM approach to the lunar surface. They have NO GRAPH for Apollo 11's journey to the Moon OR THE RETURN. They have no information about tracking Apollo 10 either. How very strange.
It may be strange to you, but as I've said, so what?
We knew where they were, very precisely, what they were doing, and everything else. It was our mission. We were the ones who needed to know...and if you think the Soviets didn't have an idea what we were up to, or didn't verify through their own accomplished network that we were in fact doing it, you are sadly mistaken.
I could personally care less whether Jodrell Bank has a graph of AS-11's approach to the lunar surface. It doesn't matter. They weren't a part of MSFN...and MSFN was the link to the Apollo spacecraft the whole way...a world wide network of communications, data, and tracking stations that fed us everything we needed to know about everything. We had Honeysuckle Creek, Carnarvon, Madrid, Goldstone, Parkes, Guam, OTC, Canberra, Sydney, the ARIA, ships, good lord...it was the most extensive network on the planet!
People all over the world were involved.
Independent verification?
The very idea is ludicrous. Half the world got involved in Apollo.
