It seems to me that LNT is definitely wrong, there is a threshold. The question is.. what is that threshold Coincidentally, my brother was a PhD in Zoology and his doctorate thesis back in the 1960s was whether or not there is a threshold for radiation damage on fruit-flies. His results indicated that there was no threshold. Radiation damage is proportional to the dosage. Nature, 1961 "Radiosensitive Stages in the Spermatogenesis of Drosophila melanogaster" - Strangio, V. A. The actual thesis is a bit too technical for my complete understanding.
