Prof Geraldine Thomas promoting nuclear industry in South Australia, but no always accurate

Steve Dale Nuclear Fuel Cycle Watch South Australia, 1 Oct 16 In Geraldine Thomas’s recent talk she showed dosimeter data from students in Japan, but she didn’t make it clear that the students were kept out of the “Restricted zone” (funny about that). But if you read the paper, it mentions that a teacher went into the zone for 2 hours (to Okuma) and had readings of 5 microSieverts per hour. Thought I would show how the graph would look with this data included. (Note: Okuma is not the “hottest” area, some areas in the restricted zone are over 20 microSieverts per hour) [relevant graph can be seen on original on Facebook] Facebook https://www.facebook.com/groups/1021186047913052/ 

Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus—the ‘D-shuttle’ project— N Adachi1, V Adamovitch2, Y Adjovi3, K Aida4, H Akamatsu5, S Akiyama6, A Akli7, A Ando8, T Andrault9,H Antonietti3 Show full author list  27 November 2015  Journal of Radiological Protection, Volume 36, Number 1

Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter ‘D-shuttle’ for two weeks, and kept a journal of his/her whereabouts and activities.  The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries………..

A large value of 5 μSv h−1 was recorded for one participant from Fukushima high school (figure10 top) [on orioginal]. This was when this person (teacher) visited Okuma town in the restricted zone, close to the Fukushima Dai-ichi Nuclear Power Plant (figure 1) for research purposes. For two hours, 15:00 and 16:00, high hourly doses were recorded, and this coincided with the activity journal entry of this person……..http://iopscience.iop.org/article/10.1088/0952-4746/36/1/49
