Visualization of Radioactive Substances
with JAXA's 'Ultra-wide-angle Compton Camera'

The Japan Aerospace Exploration Agency (JAXA) has constructed a prototype of a
new device called the "Ultra-wide-angle Compton Camera," which can visualize
radioactive substances that emit gamma rays. The camera was developed by
applying technology for a gamma-ray observation sensor that will be installed
in the next generation X-ray astronomy satellite "ASTRO-H."
This device combines the power of a wide-angle vision covering almost 180
degrees, and a nuclide whose unique feature is identification of gamma-rays,
in order to visualize the distribution of Cesium 137 (Cs-137) and 134 (Cs-134)
in any plot of ground or a house lot. Hence it can be utilized to obtain images
of radioactive substances accumulated on rooftops
and other raised locations
that are difficult to survey using conventional investigation methods by human
beings with a survey meter.

On February 11, JAXA, the Japan Atomic Energy Agency (JAEA) and Tokyo Electric
Power Company (TEPCO) conducted a demonstration of dosimetry and imaging using
the Ultra-wide-angle Compton Camera in Kusano district, Iidate Village,
Fukushima Prefecture, an area which is designated as a planned evacuation zone.
We were able to successfully capture high precision images of radioactive
Cesium distribution with a much wider view as compared to that of a
conventional gamma-ray camera.

JAXA and JAEA, in cooperation with TEPCO, will carry out further studies of
possible practical uses of the Ultra-wide-angle Compton Camera for
decontamination of radioactive substances and other related operations.
