BOPI 01 BR / 2025 REPERTOIRE NUMERIQUE 16 (73) PERI SE, Rudolf-Diesel-Strasse 19, 89264 WEISSENHORN (DE) (74) ALEMBONG OSWALD AMIN, S/C Von Seidels Cameroon Sarl, EasyOffice Building, Centre de l'Artisanat, Carrefour Intendance, B.P. 30188, YAOUNDE (CM). (57) The present disclosure relates to a grid beam slab formwork (100) comprising of primary beams (104), secondary beams (106), multi-level drophead unit (102), and props (118). The multilevel 5 drophead unit (102) offers up to or more than six connection points for the primary beams (104) and the secondary beams (106). The multilevel drophead unit (102) allows the construction of an additional structure that otherwise requires a separate drophead or an adaptor thereby reducing an overall cost associated with the formwork. Moreover, the multi-level drophead unit (102) enables the creation of the platform wherever needed. On the other hand, the adapter (116,301) 10 prevents entrapment of the sheathing members, such that the beams can be removed when the concrete has achieved required strength and the load can be taken by the props (118). ________________________________________ (11) 21764 Consulter le mémoire (51) G01N 33/24 (2019.01) (21) 1202400080 - PCT/EP2022/074644 (22) 05/09/2022 (30) FR n° FR2109325 du 06/09/2021 (54) Method for assessing the uranium content in a borehole using gamma spectrometry and associated device.

(57) The invention relates to a method for assessing the uranium content in a region of interest (10) of a subsoil (11) using gamma spectrometry, the method comprising the following steps: (a) acquiring at least one energy spectrum of gamma radiation associated with the region of interest (10), the energy spectrum comprising at least one low-energy band, one high-energy band, a contribution of the self-attenuation of uranium in the low-energy band being greater than a contribution of the self-attenuation of uranium in the high-energy band, (b) assessing the uranium content in the region of interest (10) using the area of the low-energy band, the area of the high-energy band of the energy spectrum acquired in the region of interest and at least two calibration coefficients.
