You mention specific readings from Orion. I emailed project Orion but they have not gotten back to me about what their data shows would be the radiation levels on the Apollo trajectory. I'm quite certain they do have that data. There are two probes in elliptical orbits that collected extensive radiation data of every part of the Van Allen belt. That data is there, and I really want to know what its saying the radiation levels are on the Apollo trajectory. So far, no luck. I'm surprised nobody has already done this given its by a very far margin the most powerful argument for the moon landings having been a hoax. It wouldn't end my study thought because they still may have faked the data.
I'm on the fence on whether they landed on the moon and believe the video may have been faked for the purpose of keeping any secrets

The BIRD data provided a preview of the radiation environment that the crew will encounter while transiting the trapped radiation belts on future exploration missions. Prior to entering the trapped belts, the undulation of the GCR as a result of the varying intensity of Earth’s geomagnetic field is observed in Figure 12. Upon entering the trapped belts, a region of high absorbed dose rates was encountered, followed by a local minimum, caused by a softening of the trapped proton energy spectrum. The second region of high absorbed dose rates occurred just after the maximum altitude was reached. The maximum absorbed dose rate was found to be about 1 mGy/min, 20 times the alarm level for the ISS-TEPC.
It is important to note that while these absorbed dose rates are very high, the exposure is transient. For nearly 4.5 hours of mission time, the total absorbed dose to the detectors was less than 20 mGy (water). The results for the BIRD detectors compare favorably with the RAM results, as shown in Table 1. Differences on the order of 10%-15% for co-located RAM and ISS-TEPC detectors are common on the ISS. It is also interesting to note that the cumulative absorbed dose as measured by the ISS-TEPC during the EFT-1 mission was about three orders of magnitude, or 1000 times, less than the cumulative absorbed doses measured on the Orion MPCV.
Here is what I would find convincing: A map showing how many hours it would take for an LD50 level of radiation at each point on a 2D map showing a hemispheric slice of Earth using Orion data. Of course as the Orion project has pointed out repeatedly, the dose will change over time. However, an average is good enough to get an idea.

It has been claimed that solar flares occurred during the Apollo missions that would have been quite dangerous to the astronauts. I believe all the data should be out there to do the analysis on those flares and what impact they would have on a lightly shielded astronaut.

Apollo went through the thinnest part of the belts.
If Apollo really did go through the 'thinnest' part of the Van Allen radiation belts someone should have told astronaut Alan Bean.
He doesn't seem to know they even exist (edit: doesn't know where they are) Seems a little underprepared for an Apollo astronaut don't you think? (good bit starts at 36 seconds in)

Dishonest editing when asking him about his Skylab mission.
What basis do you have for the color of the antenna?

The antenna is silver and will reflect what''s around it which will affect how it appears in a photograph. Add in variations of angle, focus and motion blur and you'll get variations in how it appears in a photo.
Seriously what areally you trying to argue here? That there are different antennae? No antenna? What?

The idea that an antenna can appear dull black and 12mm to 14mm in one photo, but a chrome/metalic 2mm to 3mm in another photo is a factor of six difference. While its true antenna can appear different widths based on circumstance, I disagree strongly that antenna can appear six times thicker in one photo, especially where it does not appear glare is involved.
