“Tokyo 2020 – The Radioactive Olympics”

“Even places that have undergone extensive decontamination efforts could be recontaminated at any time by unfavourable weather conditions, as mountains and forests serve as a continuous depot for radioactive particles.”


Tomorrow in one year, on March 26 2020, the Olympic torch relay will start in the radioactively contaminated Fukushima Prefecture. This is why tomorrow, a group of anti-nuclear oranizations in Germany, Switzerland, France and Japan will launch an international information campaign entitled „Tokyo 2020 – The Radioactive Olympics”. The campaign will focus on the ongoing radioactive contamination of parts of Japan due to the nuclear catastrope of Fukushima, which began eight years ago.
Dr. Alex Rosen, chairman of the German affiliate of the International Physicians for the Prevention of Nuclear War (IPPNW), one of the principal organizations behind the campaign explains: „We are concerned about the health consequences of radioactive contamination, especially for people with increased vulnerability towards radiation, such as pregnant women and children.“
International regulations limit the permitted dose for the general public of additional radiation following a nuclear accident to 1 mSv per year. “In areas where…

    The effect of ionising radiation exposure on dementia is approached by applying the causation models of John Stuart Mill and of Sir Austin Bradford Hill to mechanism and epidemiological evidence. Since ionizing radiation is known to kill brain cells in laboratory culture and to affect hippocampal neurogenesis in animal experiments at modest doses, it is reasonable to assume that exposure to radiation must affect neurological integrity and hence dementia rates in those who are exposed. There is persuasive evidence from the epidemiological studies of a large cohort of female nuclear workers that ionising radiation exposure is associated with significant low dose region dose-dependent increases in rates of dementia. Using results from these studies, the Probability of Causation approach (PC), conventionally employed for assessing cancer risk following radiation exposure, is extended to dementia to find a risk coefficient for all ages of 60 per Sievert cumulative exposure over the range 0-100 mSv. The finding suggests that natural background external exposures to ionizing radiation are partly responsible for the development of dementia in human populations. A simple general model for dementia is proposed.

    1. IntroductionDiscussion of the health effects of ionising radiation (IR) has, until recently, focused on cancer and genetic damage as assessed largely through the concept of “absorbed dose” and rates of illness and congenital effects revealed by the Japanese Life Span Study (LSS) of the survivors of the Hiroshima and Nagasaki bombs. Indeed, the currently accepted cancer risk and genetic risk per unit dose applied by governments, following advice from radiation risk agencies like the International Commission on Radiological Protection (ICRP), is largely based on the LSS [1]. The conclusions and the safety of the LSS studies will be revisited here. However, it is increasingly clear that IR exposures cause heart disease, and a wide range of other conditions. Indeed, evidence has accumulated to the effect that IR has an impact on most organs and systems of the body through what can be broadly described as “premature ageing” [2]. One of the most-age related and serious conditions increasingly found in human populations is dementia. Dementia, is now the 4th leading cause of death in the USA, the leading component of dementia being Alzheimers disease [3]. There is now considerable evidence that exposure to ionizing radiation can lead to the development of Alzheimers disease and to dementia [4]. Evidence includes results from high dose radiation therapy for brain tumours [5] [6] [7] but also from low dose exposures from e.g. CAT scans and from studies of nuclear workers which will be discussed below. The issue of causation, and the risk of dementia from IR are approached here through a consideration of mechanism, laboratory and epidemiological evidence, using the philosophy of causation as presented by the classic work of Mill [8] and Bradford Hill [9].


  2. Interesting snippet from the report: https://ippnw.de/commonFiles/pdfs/Atomenergie/Tschernobyl/Report_TF_3005_en_17_screen.pdf Page 79 – Outlook
    “Organizations like the IAEA are not motivated to protect the health of the population; their interests lie largely in protecting the profits and political influ-ence of the nuclear industry in Japan and the world. While the Japanese nuclear power sector has generated immense profits with its aging reactors for decades, the cost of the extensive decontamination and clean-up attempts in Fukushima will be shouldered by generations of Japanese taxpayer”
