I've done a further bit of searching on radiation, and came up with this video, an actual NASA video, 30 minutes long, talking about the radiation danger, and how they cannot go to the Moon or Mars until they have come up with a solution to this problem!
That left me open-mouthed, as you can imagine, and I patiently waited for mention of the Apollo missions, and how the astronauts were affected. The whole atmosphere of the video was unreal... Apollo was just brushed over, barely mentioned, except to note that a Coronal Mass Ejection was emitted from the sun between Apollo 16 and 17, and how that would have been a danger to the astronauts, had they been on the surface at the time. However, the focus was on the future, not on the past, and no mention was made whatsoever of any health effects on the Apollo astronauts, no follow up medical tests, nothing! It was surreal! It was as if the Apollo program had never existed. Have a look for yourself and see what I mean.
Scroll to the bottom and watch program 25 - it runs for 30 minutes.
