In autumn 2017, small amounts of Ruthenium-106 of unknown origin were detected in Europe by several independent monitoring networks. To study the dispersion of this radionuclide, inverse modelling methods are applied to retrieve the location, time, d

Bayesian transdimensional inverse reconstruction of the Fukushima Daiichi caesium 137 release

Autor: Joffrey Dumont Le Brazidec, Marc Bocquet, Olivier Saunier, Yelva Roustan

The accident at the Fukushima Daiichi nuclear power plant (NPP) yielded massive and rapidly varying atmospheric radionuclide releases. The assessment of these releases and of the corresponding uncertainties can be performed using inverse modelling me

The Fukushima-Daiichi accident involved massive and complex releases of radionuclides in the atmosphere. The releases assessment is a key issue and can be achieved by advanced inverse modelling techniques combined with a relevant dataset of measureme

International audience; From early April 2020, wildfires raged in the highly contaminated areas around the Chernobyl nuclear power plant (CNPP), Ukraine. For about 4 weeks, the fires spread around and into the Chernobyl exclusion zone (CEZ) and came

Bayesian inference and uncertainty quantification for source reconstruction of radionuclides release: application to recent European radionuclide detection events

Autor: Joffrey Dumont Le Brazidec, Marc Bocquet, Yelva Roustan, Olivier Saunier

In case of an accidental radioactive release, the Institute for Radiological Protection and Nuclear Safety (IRSN) uses atmospheric dispersion models to assess radiological consequences for human health and environment. The accuracy of the models’ r
