  • The scientific community is not a unified body, so having scientists questioning any scientific model does not seem like a “wow” moment. But, when the discourse starts including strong vocabulary, admittedly I start questioning/researching claims. And I appreciate it when studies conclude by saying things like: cautious of interpretation is needed, or further studies are warranted, etc.

    Apart from that, sure, maybe the LNT model needs some re-evaluation, maybe not - I dunno, time will tell. Still, to my understanding, one problem with ionising radiation is that the dosage received by people is not always as tightly controlled as needed for it to be safe, despite all efforts. Not even in work environments.

    For example:

    A total of six studies (covering 3,409,717 individuals), which were published between 2006 and 2021 from 4 countries met the inclusion criteria. (…) Pooled analyses indicated that occupational radiation exposure was associated with a 67% higher risk of thyroid cancer

    The researchers assembled a cohort of more than 300,000 radiation-monitored workers from France, the United Kingdom and the United States, employed at nuclear facilities between 1944 and 2016. (…) The study revealed a positive association between prolonged low-dose exposure to ionizing radiation and mortality from these hematological cancers. The study concluded that health risk remains low at low exposure levels. Nevertheless, the evidence of associations between total radiation exposure and multiple myeloma and myelodysplastic syndromes signals the necessity for future radiation studies to expand the discussion on radiation protection and occupational safety measures on a global scale.


  • - If I got this right, from in table 1, p3 one could get to the conclusion that to decommission photovoltaics creates 7 times more CO2 (more precisely g CO2e/kWh), than decommissionning a nuclear plant for decades, as shown above. It made me wonder how they arrived to these measurements. But the link to the study for the nuclear is dead (see Heath, Garvin A., and Margaret K. Mann. 2012). So this cannot be verified.

    • Having a potential solution in the works for nuclear waste is very different from what you said, which was: Nuclear waste is not and has never been a real problem.

    Bye-bye now

    Edit: The strikethrough, because it looks like the decommissioning of nuclear power plants was not reliably assessed after all. To be more precise, this is the 2012 meta study that is used for the g CO2e/kWh from nuclear decommissioning, and that I had difficulty finding. It clearly states:

    Decommissioning was not usually described in detail; when described, most seem to closely resemble only “immediate dismantling,” not full decommissioning (see the Downstream Processes section of the supporting information on the Web).

    Thanks for this, it’s the first time I hear about this and it certainly sounds very interesting. I’m gonna look more into this as soon as I find the time. In the meantime, if you know more about them and feel like sharing about your experience using them, or anything actually, I’ll be glad to have your input.

    May I also suggest something? Perhaps add in the post title something like anti-marketplace or anything like that, so that it is a bit clearer what they are for those of us who don’t know. (English is not my first language and just woke up, but still silly me, by reading the title I thought they were currency exchange apps. And now my coffee is ready!)








  • Fukushima Contaminated Water Risk Factor: Global Implications | February 12, 2025 | published by Environmental Science & Technology, Vol 59/Issue 7

    Synopsis

    The disposal of Fukushima’s contaminated water poses profound and potentially catastrophic risks to the environment, possibly exceeding initial expectations.

    Abstract

    The discharge of Fukushima radioactively contaminated water into the Pacific Ocean started in August 2023, posing comprehensive threats to marine ecosystems and human health globally. This study introduces the Fukushima Contaminated Water Risk Factor (FCWRF), which integrates three components─radionuclide diffusion, bioaccumulation, and global seafood trade─to evaluate the spatiotemporal distribution of risks based on actual discharge practices. Results suggest that comprehensive risks exceeding 2 orders of magnitude beyond the baseline will be transferred to six continents globally. Furthermore, the spread of such risks is projected to be six times faster than radionuclide diffusion. In the simulation, the results illustrated a small increase in radionuclide activity occurring in most regions of the Pacific Ocean. Nevertheless, the dimensionless FCWRF based on a novel integrated framework bridges the barriers among different fields in the risk assessment of radionuclides, thereby underpinning timely and effective responses from the global community.
