The Fukushima Dai-ichi Nuclear Power Station accident, caused by The
Great East Japan Earthquake, has resulted in leakage of radioactive
materials and contamination of the environment. Separating highly-contaminated
dirt from the total amount of dirt removed for decontamination makes
it possible to reduce the volume of dirt that needs to be stored.

Tokai Power Station (TPS) of THE JAPAN ATOMIC POWER COMPANY (JAPC)
started the commercial operation in 1966. JAPC is now dismantling by
themselves after the commercial operation stop in 1998. Kawasaki Heavy
Industries, LTD (KHI) took part in the construction of TPS and manufactured
and maintained its primary system including the heat exchangers (SRU).
KHI cooperated with JAPC's decommissioning construction and finished
install of SRU dismantling components.
The purpose of this In-Vivo Counter is; a) to use for radiation control at the time of nuclear disaster at Hokkaido Power Electric; and b) securing equipment to offer to disaster site including nuclear facilities other than Hokkaido Power Electric at the time of nuclear disaster (based on "Cooperation Agreement among Nuclear Operators at Nuclear Disaster"). Fuji Electric developed and delivered In Vivo Counter, which provides detection of trace amount of radionuclide in body of personnel working in Tomari Nuclear Power Plants (Hokkaido Electric Power Co., Inc). This In Vivo Counter has a feature to ease the transportation effort to disaster site, which is able to disassemble, transport, and re-assemble easily, in case of nuclear disaster is happened, securing radiation characteristics as conventionally installed equipment.

This paper provides the policies and results working on the issue of environmental pollution at Map Ta Phut Industrial Estate in Thailand. For the issue, we have installed environmental monitoring systems, standardized the operating procedures for environment measurement and held training events for the system operators of Industrial Estate Authority of Thailand. For research part, we have installed IT infrastructure at Chulalongkorn University for environmental research and held training events for Thai researchers. As a result, IEAT became able to grasp the status of pollutants such as volatile organic compounds and to disclose the status for risk communication at Map Ta Phut Industrial Estate. In addition, Thai researchers became able to research for environmental improvement including air pollution by themselves.
