Development of the ultra-compact KURAMA-II
We have developed the ultra-compact KURAMA-II, a much smaller version of the conventional KURAMA-II, to realize flexible monitoring immediately after the occurrence of a nuclear disaster.
KURAMA
KURAMA (Kyoto University RAdiation MApping system) is a GPS-linked automatic radiation measurement system newly developed by the Kyoto University Research Reactor Institute (at the time of development) in response to the accident at the TEPCO's Fukushima Daiichi Nuclear Power Station.

KURAMA Overview
KURAMA is a system that not only measures dose rates, but also quickly shares information obtained from detectors and provides other data for advanced analysis, and has the following features.
Small and lightweight
The onboard device is compact and lightweight and can be carried with one hand.
Fully automatic measurement
No operation is required for measurement. Measurement starts automatically when power is turned on and ends when power is turned off.
Spectral data acquisition is possible
Since γ-ray spectral data is acquired, not only can various dose rates be calculated, but also the information necessary for nuclide identification can be obtained.
Flexible hardware configuration
It is possible to change the type and configuration of radiation detectors according to the purpose and to acquire data from sensors other than radiation detectors via a variety of interfaces such as USB or serial.
Data management in the Cloud
Acquired data is transmitted using WebService and is ready to be shared and utilized in real-time on the cloud. It can also be integrated with other radiation monitoring systems.
Large-scale and Long-term monitoring activity results
It is used for various monitoring activities by national and local governments, including a wide-area driving survey of the entire East Japan region by the national government.
Development of compact and lightweight portable monitoring posts
To realize flexible monitoring immediately after the occurrence of a nuclear disaster, we have developed a compact and lightweight monitoring post based on the conventional KURAMA-II.
Visualization of cesium concentration in farmland contaminated with radioactive materials
We have developed a robot that visualizes in real-time simply by traveling with a tractor utilizing KURAMA-II. The robot is also equipped with soil fertility evaluation technology using optical sensors, which is expected to contribute to the recovery of fields where soil fertility has declined due to decontamination.
Radiation Mapping Workshop
Since the accident at TEPCO's Fukushima Daiichi Nuclear Power Station, various radiation dose mapping systems have been developed, and new technological developments have progressed beyond mere two-dimensional plots to include changes over time, spectral analysis, spatial distribution estimation, and an expanded range of measurable dose rates. We hold workshops to share the latest trends in it, discuss issues, and promote collaboration and fusion with other fields.
