[Report] Kanagawa Prefecture / Shizuoka Prefecture Boundary Soil Collection Caravan Results Report
June 5, 2018, soil sampling caravan of blank range near Kanagawa Prefecture and Shizuoka prefectural border, gave a six collection. Two secretariat staff and volunteer Y living in Kanagawa prefecture as a driver helped. Thank you for your cooperation, Mr. Y.
The area this time is the area where it is assumed that the plume passed a little darker in the "Hayakawa map" and soiled. I would like to verify that by actual Becquerel measurement.
In order to prevent the suction of dirt when collecting it, a mask was used for protection. The weather was fine on the day, and it was sunny several days before, so the soil was dry and the collection progressed smoothly. We put on a screen (sieve) on the spot and made it possible to measure as it was, and we brought it to the "East Forest Measurement Room" in Kanagawa Prefecture and requested measurement.
The measurement results are as follows.
In Manazuru and Odawara, we have confirmed the value of more than 400Bq / kg in 2018 the current was measured.
● Cesium 134 + 137 totaling map corrected to number as of 2018
● Cesium 134 + 137 totaling map which we corrected in figure in 2011

<Discussion>
Although this measurement caravan found that there are variations in cesium concentration depending on the location, seven years after the accident , more than 400 Bq of cesium can be detected at multiple locations, and the deposition of plume can be supported in this area. You can see it as a result.
Currently, everyone's data site is working on the compilation of "Atlas" (Soil Contamination Map Book), which will be the compilation of this soil project. The results of this caravan will be added as part of the analysis to support the simulation results of plume movement at the time of the accident.
Another area, the northern part of Nagano Prefecture, is also planning additional sampling to confirm plume movement. Here too, the staff of Takasaki's measurement room does the measurement by sewing the gap of the rainy season. We will report the results here soon.
In addition to these data supplementing activities, we are actively working on the writing of Atlas manuscripts in order to make it easy to understand to everyone from various angles such as commentary of 17 prefectures and summary of measurement results in each measurement room and the situation of food contamination. I'm here.
Thank you for your continued support.
