Heh, yeah, it's not a great read, the writing style feels like a 14 or 15 year old, and I don't think it's just the translation (which doesn't look like it was done professionally, given some of the word/phrase choices - addendum; from flicking through, looks like he did the translation himself, judging by a comment at the end).
I'd already seen his 'work' on Lunar Laser Ranging, bounced it of some people who actually perform LLR. They had a good laugh.
For anyone interested, there is a free extract of the book, 1st twelve pages and some of the appendix, at
https://www.researchgate.net/publication/383213710_Apollo_11_-_The_Real_StoryThe history of rocketry is... accurate, although I find some of the choices and comparisons odd. I think I just got through the VAB/radiation section, about three pages, and after reading it twice, I'm still not sure what the conclusion is! There's references to alpha and beta particles, but also trapped gamma and x-rays, plus solar storms, thickness of the hull, path taken, a fictional account of a manned lunar mission from a German magazine, and even that, apparently, radiation stopped being a concern because NASA stopped mentioning it, but there is no actual conclusion, neither a 'radiation should have been a problem' or 'radiation didn't turn out to be a problem' to be found.
I've had a few back and forth's with the author in a Facbook group, and I was promised evidence and numbers, but so far, they are very lacking, to the point of almost non-existent.
