Radioactive contamination in the Tokyo metropolitan area in the early stage of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident and its fluctuation over five years

Geographical distribution of the ^134+137Cs precipitation referred to the aircraft monitoring results by the MEXT of Japan on December 16, 2011 [30]. Adapted from ‘Extension Site of Distribution Map of Radiation Dose, etc.’ (http://ramap.jmc.or.jp/map/).

The activity and inventory of radioactive material in the eastern part of Tokyo tended to be high… The radioactive plume with high 131I activity spread into the Tokyo metropolitan area…

Almost no public information about the radioactive contamination in the Tokyo metropolitan area and Kanto district had been shared…

The plume containing a large amount of radioactive material drifted into the Tokyo metropolitan area… where over 30 million residents live… [Publications] include almost no discussion of the fact that radioactive materials were carried into the Tokyo metropolitan area…

The contamination level was extremely high in a roadside ditch sludge in Kashiwa City…

The quantity of 134+137Cs deposited in the region studied was estimated… from values measured in the soil, it was estimated as 5.35 TBq…

High activities and inventories of the radionuclides were found in eastern Tokyo and northern Chiba… The contamination was even higher in the adjoining northern part of Chiba located east of Tokyo…

The results reveal that the Tokyo metropolitan area even now continues to be affected by radioactive contamination caused by the FDNPP accident…

Gordon Edwards, Ph.D, nuclear expert, 2017 (pdf): Intensive contamination extends over 200 km south – right down to the outskirts of Tokyo

IRSN, 2016 (pdf): Fukushima-Daiichi Accident: Main contamination events… Event of 14-16 March – This event is marked by turning winds and by a rainfall that generated significant contamination of the Japanese territory. On the evening of the 14th of March, a first radioactive plume was transported by winds towards the southwest… and reached the Tokyo area. At Tsukuba, 153 Bq/m3** were measured…

** 153 Bq/m3 = 153,000,000 uBq/m3 Cs-137 in Tsukuba after Fukushima vs. 1.2 uBq/m3 Cs-137 in Tsukuba before Fukushima (source) = 127,500,000 times higher Cs-137 after Fukushima

Another glossy new nuclear film advertisement – “The New Fire”

Film review: ‘The New Fire’ and the old Gen IV rhetoric Author: Jim Green ‒ Nuclear Monitor editor NM866.4751, October 2018 The New Fire is a pro-nuclear propaganda film directed and produced by musician and film-maker David Schumacher.It’s similar in some respects to the 2013 film Pandora’s Promise.1,2 The New Fire premiere was held in October 2017 and it can be streamed online from 18 October 2018…..

The film includes interviews with around 30 people (an overwhelming majority of them male) interspersed with footage of interviewees walking into buildings, and interviewees smiling. The musical underlay is a tedious drone ‒ a disappointment given Schumacher’s musical background……..Interviewees are mostly aging but the film’s main message is that young entrepreneurs may save the planet and its inhabitants with their Generation IV reactor projects……..

These climate heroes are contrasted with anti-nuclear environmentalists. One interviewee says that “people of our generation are the first ones that have the opportunity to look at nuclear power without all the emotional baggage that previous generations have felt…..

Another interviewee attributes opposition to nuclear power to an “irrational fear of the unknown” (which surely poses a problem for the exotic Generation IV concepts promoted in the film) and another says that “once people sort of understand what’s going on withnuclear, they are much more open to it”.

The film trots out the usual anti-renewables tropes and falsehoods: 100% renewables is “just a fantasy”, renewables can contribute up to 20% of power supply and the remainder must be baseload: fossil fuels or nuclear power………

Accidents such as those at Fukushima and Chernobyl get in the news because they are “so unusual” according to interviewee Ken Caldeira. And they get in the news, he might have added, because of the estimated death tolls (in the thousands for Fukushima5, ranging to tens of thousands for Chernobyl6), the costs (around US$700 billion for Chernobyl7, and US$192 billion (and counting) for Fukushima8), the evacuation of 160,000 people after the Fukushima disaster and the permanent relocation of over 350,000 people after the Chernobyl disaster…….

Transatomic Power’s molten salt reactor concept The film spends most of its time promoting Generation IV reactor projects including Transatomic Power’s molten salt reactor (MSR) concept. [Ed note. recently failed and abandoned] .

Scott Nolan from venture capital firm Founders Fund says that Transatomic satisfies his four concerns about nuclear power: safety, waste, cost, proliferation. And he’s right ‒ Transatomic’s MSRs are faultless on all four counts, because they don’t exist. It’s doubtful whether they would satisfy any of the four criteria if they did actually exist……. https://nuclear-news.net/2018/10/01/another-nuclear-film-advertisement-the-new-fire/
