@article{Blatman2016ProbabilisticRB, title={Probabilistic risk bounds for the characterization of radiological contamination}, author={G{\'e}raud Blatman and Thibault Delage and Bertrand Iooss and Nadia P'erot}, journal={EPJ Nuclear Sciences \& Technologies}, year={2016}, volume={3}, pages={23} }

The radiological characterization of contaminated elements (walls, grounds, objects) from nuclear facilities often suffers from a too small number of measurements. In order to determine risk prediction bounds on the level of contamination, some classic statistical methods may then reveal unsuited as they rely upon strong assumptions (e.g. that the underlying distribution is Gaussian) which cannot be checked. Considering that a set of measurements or their average value arise from a Gaussian…

Statistical characterization of radiological contamination with small data samples

- Computer Science
- 2018

This paper presents several alternative statistical approaches which are based on much weaker hypotheses than the Gaussian one, which result from general probabilistic inequalities, and are applied to several data sets obtained from real radiological contamination measurements to provide more realistic risk bound estimation.
