To enhance the counter capability against terrorism in major public events, the Japan Atomic Energy Agency (JAEA) has started developments of monitoring technique that covers wide-area and rapidly detects nuclear and radioactive materials. In this project, we are developing widely applicable radiation mapping device by combining with positioning sensors and a network device. Mapping tests inside and outside of the building by using the device to locate areas with high radiation count has been performed. Also, fast neutron detection technique using plastic scintillation detectors is being developed for detection of neutron sources including nuclear materials. Measurement with two rod shaped detector that placed into a cross showed better localizing capability compared with single detector. In this report, recent progresses of the project are given.
