137. Linking speciation and soil-water-plant transfers of natural radionuclides in a wetland impacted by a former U mine: recent advances from the pluri-disciplinary and multi-partners project INSPECT-NEEDSclides in a wetland impacted by a former U mine: recent advances from the pluri-disciplinary and multi-partners project INSPECT-NEEDS

Invited talk

Main sources of radioactivity in the environment are natural radionuclides (RNs) which are ubiquitous in all Earth's surface ecosystems, i.e., in air, soils, waters, and living organisms including Humans, as terrestrial RNs (uranium-238, uranium-235, and thorium-232 from geochemical background and their radioactive daughters) or cosmogenic RNs (e.g. carbon-14). However, during last decades,...

81. Biogeochemical behaviour of tellurium (Te) and caesium (Cs) at the continent-ocean interface: preliminary scenarios for accidental radionuclide releases

ORAL

Radioactive tellurium (Te) and caesium (Cs) are fission products in nuclear power plants (NPP) emitted during accidental events (i.e., Chernobyl-1986, Fukushima-2011)[1]. Post-accidental models describing their fate and dispersion in natural environments require the understanding of the biogeochemical behaviour of their stable homologues. However, stable Te and Cs are poorly studied in aquatic...

136. In situ ATR - FTIR study of uranyl sorption at illite - solution interface in the presence of phosphate ions

ORAL

Introduction: Gaining insights into mechanisms and species of uranyl sorption onto illite, at a realistic and low concentration of uranyl in the micromole range per liter, is highly needed for providing refined mechanistic process understanding of radionuclide retention in clay systems. Moreover, studying uranyl sorption processes due to the presence of aqueous ligands (such as phosphate) is...

141. Environmental Radiological Baseline for Unconventional Oil and Gas Zones in Mexico

Mme BEATRIZ HERNÁNDEZ MÉNDEZ (ININ)

ORAL

The natural radiation level in a given site can be changed by NORM material generated by the oil, natural gas, copper, silver, uranium and lithium mining industries, among others. In Mexico there is no baseline of natural radiological levels but there is exploitation of energy resources by the industry and there is a possible extraction of unconventional hydrocarbons (UHC). This work deals...

48. Fraudulent exams in the training of reactor supervisors at the Laguna Verde Nuclear Power Plant- México

Dr Bernardo Salas Mar (National Autonomous University of Mexico)

ORAL

In both the nuclear and aeronautical industries, operator training is necessarily rigorous and permanent due to the risks of an accident and its consequences. However, at the Laguna Verde Nuclear Power Plant (LVNPP), this statement was questioned after a group of five candidates presented an exam for Reactor Supervisor, and it was discovered that one candidate left on a computer where the exam...
