I still don't understand where you are getting your atomic bomb figures from, I have a masters in History majoring in Japan and you do not have an atomic bomb level of radiation and don't really seem to understand what that even implies. Yes you have received radiation similar to that of people living a fair amount away form the epicentre of the blast in hiroshima, who like I told you showed a 1.8% increase in cancer rates (or otherwise put 98.2% chance of not getting cancer from the dose) and that is a dose under 50msv, received all at once, full body, 60 years ago when health standards were not what they are today. Atomic bomb level radiation where most incidence of cancers, which was still a relatively small amount, was over 100msv and is the reason the linear extrapolation theory exists, which like I said before is pseudoscience and not fact. Furthermore, atomic bomb level of radiation is the level where people got radiation poisoning and died soon after the blast, or were completely erased in an instant. You seem to have completely disregarded the facts I have shown you and chosen to pick out the bad in everything, which even for hypochondrias is a little excessive. Miners and workers in the nuclear industry receive more than you have A YEAR and their isn't a huge increase in their cancer rates. I know, it seems harsh, and I get it because obviously I have had the same fear before which is why you contacted me, but you need to try and look at it rationally and actually ingest the facts and not only look at the worse case scenario, which is also the most likely.
Again, I don't mean to seem rude because I have been where you have been, but you don't really seem to grasp radiation all that well and when there is no evidence the amount you have received will give you cancer, when compared to things like smoking and drinking and eating cured meats which has clear evidence but people do them anyway, there really is nothing to fear as long as you minimize your exposure in the future
