Abstract

Geographical location of Japan is a reason that causes this country to become one of the most disaster-prone nation in the world. The Nuclear Emergency Response Headquarters of Japan Government has established a comprehensive plan for monitoring radiation due to the Tohoku earthquake on 11 March 2011 that caused the release of radioactive materials from Fukushima Daiichi Nuclear Power Station (NPS). The main purpose of this research is to develop a prototype platform based on Open Geospatial Consortium (OGC) international standards for integrating the radiation monitoring results from Fukushima Area, Japan. Because of the monitoring data was mainly stored in XML or CSV format, this platform provided a simple and standardized environment for converting original data into uniform format with three primary information including observation time, observation locations, and observation results. After stage of data standardization, all converted data was published as services utilizing OGC standards of Catalogue Service for the Web (CSW), Sensor Observation Service (SOS), Web Map Service (WMS) and JSON-based RESTful Application Program Interface (API). Finally, this platform visualizes the monitoring results and provides a client with the functionality of time series selection. The idea of this prototype platform in releasing the radioactive materials monitoring data using international standards has matured over time and does not exclude the possibility of making it open access. The result of this study has shown that the utilization of international standard is a necessary step for data integration and data sharing.

Highlights

  • Located on the east side of Pacific Ocean, in Fukushima prefecture, Fukushima Daiichi Nuclear Power Station (NPS) a station operated by Tokyo Electric Power Company (TEPCO) is the source of emission of radioactive materials due to strong earthquake and tsunami happened on 11 March 2011 in Japan [1]

  • The Japanese government was really concerned about the level of radioactive contamination because a large area has been subject to the contamination and Fukushima residents needed to know whether their health was guaranteed [2]

  • The incident at Fukushima Daiichi Nuclear Power Station is one of the most dangerous incidents in the world in terms of nuclear power that affected a larger number of people living near the accident location due to the radioactive materials emission. It has been more than 7 years from the accident with many efforts have been conducted by the government of Japan to determine the level of radioactive contamination and how it has been affected the life of citizens

Summary

Introduction

Located on the east side of Pacific Ocean, in Fukushima prefecture, Fukushima Daiichi Nuclear Power Station (NPS) a station operated by Tokyo Electric Power Company (TEPCO) is the source of emission of radioactive materials due to strong earthquake and tsunami happened on 11 March 2011 in Japan [1]. The Nuclear Emergency Response Headquarters, from the event of Fukushima plant, has been established a comprehensive plan for monitoring radioactive substances together with many studies on contamination tracking from scientists. In the efforts of monitoring radioactive substances, Nihei in 2016 gathered samples and used a detector to discover level of radiocesium concentration on agricultural, livestock, forest and fishery products for three years from accident of NPS in 2011.
