Radia#on Monitoring

Na#onal Project to con#nuously Monitor/Construct/Publish Radia#on Monitoring Database of Fukushima Area

•  Understand what happened at the accident in the past

•  Help the decision making for the future

AIST’s Role in the Project Provide Ease-‐of Use “Modern” Sensor Data Service Framework

based on the Interna=onal Standards.

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

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

•  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.

Use Case: Combination of our SOS with other WMS data source (Weather)

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

Human exposure to natural background radia#on, 0.27uSv/h

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.

• Personal lifelogging –  Timelines of chronological sequences of ac=vity objects –  Food and exercise records, event pictures, loca=ons, etc.

•  cf) EMR(Electronic Medical Record), EHR(Electronic health record), and PHR(Personal Health Record)

– Wearable sensors, smartphones

• Open Interfaces and Data Formats –  Plaiorms and the data they expose can be controlled and delivered to the correct users at the correct =me for the correct usage through APIs

–  Ex) Sony Lifelog API: REST-‐based web-‐service API •  User profile: name, height, weight, etc. •  Ac=vi=es: steps, sleep, transporta=on, music listening, etc. •  Loca=ons: a history of where the user has been

Possible Candidates of Existing Standards to Interoperate

•  Health Domain – Health Level 7 (HL7) for exchanging health care data (https://www.hl7.org)

•  A data set to provide a snapshot in time containing a summary of the pertinent clinical, demographic, and administrative data

– Statistical Data and Metadata Exchange –Health Domain (SDMX-HD) •  SDMX: Statistical Data and Metadata Exchange (ISO/TS 17369:2005) •  WHO implementation of SDMX (summary data) to share and exchange

medical indicators and metadata between medical organizations

•  Publishing Statistical Data as Linked Data – The RDF Data Cube Vocabulary (W3C Recommendation) (http://www.w3.org/TR/vocab-data-cube)

•  Aggregate data, Numeric, Time series, Multi-dimensional tables, cubes

Conclusions

•  Fukushima Radiation Monitoring Database Project – To provide ease-of use “modern” sensor data service framework

based on OGC Standards – OWS (WMS, WFS, WPS), SOS.

•  RALFIE Framework – To assist Fukushima residents to reduce potential health effects of

radiation exposure based on life pattern mining – New fashion of OGC

•  Moving Feature, SensorThings API – Current open issues of data formats and interfaces

•  Lifelog data •  Summary data

–  Vocabulary, dimension, …
