First ever images of fuel debris fallout particles from Fukushima

Unique synchrotron visualisation techniques offer new forensic insights into the provenance of radioactive material from the Fukushima nuclear accident to understand the sequence of events related to the accident.

In April 2017, a joint team comprising the University of Bristol, the Japan Atomic Energy Agency (JAEA) and Diamond, the UK’s national synchrotronlight source, undertook the first experiment of its kind to be performed at Diamond.  A small radioactive particle (450μm x 280μm x 250 μm) from the Fukushima Daiichi nuclear accident in 2011 underwent a comprehensive and independent analysis of its internal structure and 3D elemental distribution, to establish the source of the material and the potential environmental risks associated with it.
