2015.12.12 Measure and Communicate - what worked and what didn't :測って、伝える。- で...Ryu Hayano
福島ダイアログイニシアティブ国際ワークショップ「原子力事故後の生活状況の回復」でのスライド
Slides presented at the "International Workshop on the Fukushima dialogue initiative "Rehabilitation of living conditions after the nuclear accident"
This document provides a personal recollection from a physicist named Ryugo Hayano about the 2011 Fukushima Dai-ichi nuclear accident in Japan and its aftermath. It describes the events of the accident, the radiation levels and health effects observed, the food safety testing and regulations put in place, and Hayano's role in communicating scientific information about radiation on Twitter to allay public fears in the years following the incident.
This document summarizes recent radiation measurement efforts led by Ryugo Hayano including:
1. Whole-body counter surveys of over 2700 babies and small children in Fukushima Prefecture which found nobody had detectable levels of radiocaesium.
2. Measurements using D-shuttle devices that tracked external radiation doses of French students visiting Fukushima and found no significant differences between locations.
3. An upcoming study comparing individual external radiation doses of high school students living in Japan, France, Poland and Belarus using D-shuttle devices.
Three BABYSCAN units have been deployed in Fukushima prefecture to measure internal radiation exposure in children under 130 cm. The BABYSCAN is a highly sensitive whole body counter that can detect radiation levels below 50 Bq per body. It has been used to scan approximately 1000 babies so far, and none have shown detectable levels of Cesium-134 or Cesium-137. While internal radiation exposure is scientifically unnecessary to measure, communicating the results to parents is essential to alleviate concerns about radiation exposure in their children.
1. Cesium levels in school lunches in Fukushima prefecture, as detected by whole-meal testing using gel machines, have mostly been very low or undetectable, even after Fukushima City switched to using locally grown rice.
2. Graphs are provided showing cesium detection results over time for school lunches in various cities and towns in Fukushima prefecture, with most results being below detection limits.
3. Data is available on a website for cesium detection results in school lunches from Fukushima City and other locations from 2013 to the present.
