Tepco under-reported Fukushima release of plutonium

Tepco under-reported Fukushima release of plutonium – by 200 times!

New report estimates 278 trillion Bq of plutonium released from Fukushima reactors — Over 200 times higher than amount reported by Tepco — “Highly radiotoxic when incorporated into human body” as it decays http://enenews.com/new-report-estimates-278-trillion-bq-of-plutonium-released-from-fukushima-reactors-over-200-times-higher-than-amount-reported-by-tepco?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

Evaluation of the Fukushima Accident Source Term through the fast running code RASCAL 4.2(pdf),ENEA Bologna Research Centre, May 23, 2014: This Report presents the results of the application of the fast-running US-NRC direct code RASCAL 4.2 to the estimation of the Fukushima Source Term. […] it is plausible that the ventings that TEPCO announced during the accident as being conducted from the wetwell were, as a matter of fact and because of the degraded conditions of the plants, conducted actually from the drywell. […] wetwell properties imply releases which can be several oder of magnitudes lower than those from the drywell […] it can clearly be seen that the most probable path is the combination of Drywell+Direct option […] the true venting path, i.e. from Drywell instead of from Wetwell, is an extremely important issue. […] in several instances when TEPCO tried to operate venting, in order to release pressure outside the building through the stack, it proved impossible […] there are many indications that probably the radioactive material escaped from the drywell; this may have occurred without TEPCO’s immediate knowledge and because of several factors; for example: structural damages to the pipings connecting drywell to torus room (vent piping bellows), due either to the earthquake, and/or to the too violent pressure and temperature increase in the D/W; leakages through the top head manhole, the top head flange, the piping penetrations, the electrical wiring penetrations, the personal airlocks, the S/C manholes, the machine hatches, etc. […] The value of 1%/h was chosen by ENEA because of the possible highly damaged conditions of the Fukushima NPPs due to the BDB [Beyond Design Basis] earthquake.

Environmental Science & Technology (American Chemical Society), July 11, 2014: [S]tandard alpha spectrometry techniques […] are not able […] to measure 241Pu.

Boreal Environment Research (pdf), Feb. 28, 2014: The 241Pu isotope was introduced into the environment from […] accidents that released nuclear reactor fuel, such as […] the 2011 Fukushima catastrophe. As compared with other Pu isotopes in the environment that are alpha-emitting and long-lived, 241Pu is a short-lived isotope with a half-life of 14.35 years […] 241Pu decays to the alpha emitter 241Am, that has a much longer half-life (432.2 years) and is highly radiotoxic when it is incorporated into either the human or animal body. […] The 241Pu isotope has been studied less extensively than the α-emitting Pu isotopes for several reasons. Activity concentration of 241Pu cannot be determined from the same alpha spectrum as the Pu isotopes 238, 239, and 240, and extra effort is needed in order to analyze 241Pu concentration of a sample. Actually, 241Pu emits alpha particles, but they have so low probability (0.002%) that 241Pu cannot be measured directly by α-spectrometry […]

1.This Month

Reluctantly, I have realised that the climate crisis is the most huge and urgent problem for humanity, now. This website is not able to do justice to this enormous topic. All that I can do is to pick out significant information as it arrives, and also note some, (not nearly enough) of the climate events happening.

Meanwhile, nuclear-news will focus on its original purpose, to reveal the disastrous effects of the nuclear industry, and to refute the propaganda lies from the nuclear lobby.

Before we enter “a new nuclear age” – learn from the newly declassified Chernobyl health records

April 7, 2019

Fortunately, Chernobyl health records are now available to the public. They show that people living in the radioactive traces fell ill from cancers, respiratory illness, anaemia, auto-immune disorders, birth defects, and fertility problems two to three times more frequently in the years after the accident than before. In a highly contaminated Belarusian town of Veprin, just six of 70 children in 1990 were characterised as “healthy”. The rest had one chronic disease or another. On average, the Veprin children had in their bodies 8,498 bq/kg of radioactive caesium (20 bq/kg is considered safe).

For decades, researchers have puzzled over strange clusters of thyroid cancer, leukaemia and birth defects among people living in Cumbria, which, like southern Belarus, is an overlooked hotspot of radioactivity from cold war decades of nuclear bomb production and nuclear power accidents.

Currently, policymakers are advocating a massive expansion of nuclear power as a way to combat climate change. Before we enter a new nuclear age, the declassified Chernobyl health records raise questions that have been left unanswered about the impact of chronic low doses of radioactivity on human health.
