2 AIST Na#onal Ins#tute of Advanced Industrial Science and Technology, JAPAN Mainly funded by METI (Ministry of Economy, Trade and Industry) 2200 Researchers + Suppor#ng Staffs Industrial Research Bridge between basic research and product development Cross- Domain R&D(Ex. Informa#on technology with Geoscience) 6 Major Research Area ITRI Copyright 2015 Open Geospatial Consortium OGC TC Meetings@Barcelona, Spain 2

3 Fukushima Radiation Monitoring Database Project Na#onal Project to con#nuously Monitor/Construct/Publish Radia#on Monitoring Database of Fukushima Area Radia#on Monitoring Project Structure as of 2013 Project Management JAEA 2 Teams Database Publishing Database Construc#on Nuclear Regula#on Authority(NRA), JAPAN Japan Atomic Energy Agency(JAEA) AIST 2 Teams Hokkaido University 2 Teams Understand what happened at the accident in the past Help the decision making for the future Japan Map Center (Company) 1 Team Partners Okayama- U, The Ins#tute of Sta#s#cal Mathema#cs,, OGC Copyright 2015 Open Geospatial Consortium OGC TC Meetings@Barcelona, Spain 3

4 AIST s Role in the Project Provide Ease- of Use Modern Sensor Data Service Framework based on the Interna=onal Standards. Real- Time Monitoring Posts/Sensors 4000 radia=on monitoring points in Fukushima- area Produce raw data in every 10 minutes for 3years Approx. 22million Records(as of 2013) Periodical Monitoring Result Database (Car, Helicopter, Soils etc.) 239 CSV Files (data collected by 県 or 全国 ) Approx. 17million Records 31 CSV table types (for possible one schema) Japanese characters for the a`ribute name Sensor/Database that JAEA produced => Legacy style data like CSVs. 1. Convert/Wrap Legacy sensors and data(csvs and raw data) and provide them as standard Web Services 2. Construct a data federa=on framework based on 1. Framework Easy to access/interoperate Easy to re- use Easy to combine with other geospa=al data Various Radia#on Sensors Need to handle various sensors OGC(Open Geospa#al Consor#um) Web Services Copyright 2015 Open Geospatial Consortium OGC TC Meetings@Barcelona, Spain 4

5 OGC-based Sensor Information Platforms Access Data : SOS and W*S (Sensor Observa#on Service) (Web Feature/Coverage Service) Interface to radia=on measurements Federate with other OWS servers Process Data: WPS (Web Processing Service) Spa=al & Temporal Analy=cs Produce various format KMZ,AVI etc. Client GIF89a, SVG, Flash, AVI, KMZ WPS Service Calculate Various Spa=al & Temporal Opera=ons Database/Sensor Federa#on Publish Data: WMS (Web Map Service) WMS Time of maps KMZ Rich Client with Google Earth/Map OWS Services (WMS,WFS,WCS) Sensors SOS Service O&M Client Monitoring Databases Copyright 2015 Open Geospatial Consortium OGC TC Meetings@Barcelona, Spain 5

6 Use Case: Combination of our SOS with other WMS data source (Weather) Human exposure to natural background radia#on, 0.27uSv/h Jan 1, 2013 The dose rate was rela#vely high Jan 16, 2013 The dose rate was rela#vely low when there was heavy snow Snow effect Simple overlay can be useful Copyright 2015 Open Geospatial Consortium OGC TC Spain 6

8 Health Effects caused by Radiation Exposure Radiation level The average person: 2 to 3 millisievert per year 400 millisieverts per hour at reactor No. 3 on March 15, 2011 CT scan (more than 1 millisievert) Radiation sickness: A whole-body dose of 3 sieverts (3,000 times the recommended public dose limit per year) Radiation type gamma and x-ray radiation: pass directly through the body without interacting with the tissue alpha and beta radiation: lower energy, more dangerous In the Fukushima situation the radioactive isotopes detected, iodine 131 and cesium 137, emit both gamma and beta radiation. Exposure time High radiation level during a short time > Low level dosage accumulated over time Difficulty to estimate effects of long-term and low-dose radiation, such as cancer risk, mental health, etc.!
