507. Radiochemcial analysis of long-lived radionuclides using mass spectrometry: New progress in the methodology

Prof. Xiaolin Hou (Technical University of Denmark, Center for Nuclear Technologies)

Nuclear Analytical Methods

Invited

Human nuclear activity has produced a large amount of radionuclides, some of them was released to the environment, while most of them are remained in various radioactive waste to be deposited. Among these radionuclides, long-lived radionuclides such as 14C, 36Cl, 79Se, 99Tc, 126Sn, 236U, 237Np, and isotopes plutonium, neptunium, americium and curium are most important in view of waste...

463. Determination of 129I in aerosols using pyrolysis and AgI-AgCl coprecipitation separation and AMS measurement

Dr Luyuan Zhang ( Institute of Earth Environment, China Academy of Sciences)

Nuclear Analytical Methods

Verbal

Airborne radioactive iodine is a key concern for transport and dispersion of radioactive contamination and radiation exposure evaluation during nuclear accidents and nuclear emergency preparedness. Long-lived 129I in aerosols is vital for reconstruction of level and distribution of short-lived and highly toxic 131I, as well as understanding the knowledge of atmospheric circulation process of...

506. Isolation of lanthanides from spent nuclear fuel by means of high performance ion chromatography (HPIC) prior to mass spectrometric analysis

Dr Karen Van Hoecke (Belgian nuclear research centre)

Nuclear Analytical Methods

Verbal

An important characteristic of spent nuclear fuel is its burnup, which is a measure of fissionable material consumption prior to fuel replacement. Isolation of lanthanides, most importantly neodymium, from spent nuclear fuel is necessary to determine the burnup experimentally. As an introduction, various ion chromatographic strategies for lanthanide isolation described in literature will be...

477. In-Housing characterization of a working standard americium solution

Didier MALOUBIER (CEA)

Nuclear Analytical Methods

Verbal

For many reasons the production and supply of nuclear certified reference materials is becoming increasingly difficult and expensive, some of these non-routine materials being utterly not commercially available at all. This lack of CRM may be critical for the capability of labs to support analysis.
For these reasons, many labs, especially in the field of nuclear community, are involved in this...

519. ICP-MS measurement versus radiometric detection for Radium-226 analysis in environmental liquid matrices

Ms Céline Augeray (IRSN)

Nuclear Analytical Methods

Verbal

Among the natural isotopes of radium, Radium 226 is one of the most radiotoxic agent. It is part of the decay chain of Uranium 238 and, with a half-life of 1600 years, it is the most common isotope of Radium present on Earth. Due to its chemical properties, the metabolic pathway of Radium is similar to that of Calcium and it can concentrate mainly in the bones and thus increase the internal...
