Autor: Sylvain Leblond, Pascal Fichet, Rémi Laumonier, Sophie Billon, Paul Sardini, Kimberly Colas
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry
Journal of Radioanalytical and Nuclear Chemistry, 2022, 331, pp.1075-1089. ⟨10.1007/s10967-021-08172-2⟩
International audience; A new method has been developed to image surface contamination on-site by short range radiation emitters (such as alpha or beta particle emitters). The measurement is performed in direct contact with the contaminated surface a

From Bq cm−3 to Bq cm−2 (and conversely)—part 1: a useful conversion for autoradiography
Autor: Sophie Billon, Paul Sardini, Sylvain Leblond, Pascal Fichet
Publikováno v: Journal of Radioanalytical and Nuclear Chemistry
Journal of Radioanalytical and Nuclear Chemistry, 2019, 320 (3), pp.643-654. ⟨10.1007/s10967-019-06521-w⟩
Autoradiography technique generally provides an image in cps cm−2, the conversion in Bq g−1 remaining a challenge. The Geant4 tool has been used to establish a conversion procedure based on the estimation of a key parameter, the emission fraction

Autor: Sophie Billon, Patricia Patrier
Publikováno v: Journal of African Earth Sciences. 160:103637
The Imouraren uraniferous deposit is located in NW Niger and is hosted in the fluvial Tchirezrine 2 Formation (Jurassic, Tim Mersoi Basin). High-energy facies range from medium to very coarse-grained sandstones; low-energy facies are composed of fine
