GKN is in consolidation mode. A long paper on LNT has been uploaded to the Flop book website. It pulls together all the arguments against LNT that have been made on this substack, focusing on the time dimension and repair. At 40 pages, it's far too long for a substack post. The intended audience is teachers, policy makers, and missionaries; but it requires no specialist background. The basics of radiation damage and repair are laid out in some detail. I will make up a slide show if there is demand.

I am a little confused by the dose/time frame. You refer to maximum cumulative dose of 444 Sv and bone dose of 190 Sv. However, Ra-226 decay energy is 5 MEV, which is about a pico joule. 10,000,000 Bq is the safe level. This would produce about 280 joules/year. If you say that people have 28 kg of bones and tissue affected by radiation, then this gives the 10 Gy threshold that is being discussed. I don't know how you can consider this total accumulated over a lifetime. So, is your 190 Sv actually per year?
EXCELLENT WORK! Some hopefully helpful comments.
italicized part of second sentence should read: "no matter how rapidly or slowly that dose is received or to how many people". This further emphasizes how wrong LNT is. Or instead you could say: "harm depends only on the individual's total dose". then you can leave the rest of the sentence unchanged.
Section 2.2, second sentence should read: "background EXTERNAL dose rate is as high...". It is worth noting this does not include the radon dose which would be large.
Figure 14 still has the same Cumulative Doses as Figure 13.
Also the average dose rate/day for the high dose group are 0.164 and 0.106. since the PY seem to indicate the same group of people (i.e PY doubled as expected if the group is the same).
