● Report of Ibaraki, contamination situation important point investigation area workshop (Tsukuba citizen radioactivity measurement station, Mr. Fujita)
Based on the results and analysis of previous soil measurements, we reported to Mr. Fujita of Tsukuba.
As a result of analyzing 295 measurement points in Ibaraki prefecture, it is about 8,500 Bq / kg to 22,999 Bq / kg in terms of Becquerel number when converted (attenuation correction calculation) as of 2018. For example, although there is no area corresponding to the zone where the right to reside is recognized, the area which may correspond to approximately 2,800 Bq / kg to 8,499 Bq / kg “zone where immigration rights occur” is Ryukasaki City, Takatsuki City, It was reported that each one was in Toride city. There was also a discussion of the approximate points and differences between actual and estimated values (eg aircraft monitoring results). In the second half, using data and charts, we presented the situation of plume passage at that time and the consideration on dry deposition and wet deposition, and the difficulty of evaluating the initial exposure later.
You can download the projected data from the Tsukuba Citizens Measurement Office website.
