104. ON THE APPLICATION OF AUTOMATED FUSION TO TOTAL DISSOLUTION OF DIFFERENT MATERIALS

Mirela Vasile

Radiochemistry

Poster Presentation

Fusion flux dissolution is a powerful technique for the complete dissolution of solid inorganic materials. Different automated fusion devices such as Katanax (Katanax, Canada) or Claise LeNEO (Malvern Analytical, United Kingdom) have demonstrated their successful applicability for the complete dissolution of solid materials prior to analysis e.g. by ICP MS or alpha spectrometry.
In this...

60. PRELIMINARY STUDY ON THE INFLUENCE OF FE AND NI CONCENTRATIONS ON THE QUANTIFICATION OF 55FE AND 63NI

Dr Giada Gandolfo (ENEA )

Radiochemistry

Poster Presentation

Decommissioning of nuclear facilities involves the assessment of the radioactivity inventory for, among others, waste classification and temporary storage. For nuclear fission reactors, apart from the reactor core, the main contribution to the radioactivity comes from the graphite, if present, and the construction materials (concrete, metal materials such as aluminium alloy, steel, and lead)....

59. Purification technique and radiopurity analyses of YCl3 for CLYC scintillation crystal growth

Radiochemistry

Poster Presentation

ABSTRACT

Detectors needed for rare event search experiments, like neutrinoless double beta decay, neutrino interactions and those searching for direct evidence of dark matter require a high level of radiopurity to minimize background signals thus guaranteeing a high sensitivity.
Therefore, the assessment of chemical and radio-purity of all raw materials and reagents involved in the crystal...

54. THE DETERMINATION OF AMERICIUM AND PLUTONIUM ISOTOPES IN ENVIRONMENTAL SAMPLES AND AIR FILTERS IN AUSTRIA

Radiochemistry

Poster Presentation

The radiochemical environmental monitoring program in Austria includes the measurement of radiostrontium and of the alpha emitting Plutonium isotopes in soil and vegetation. However, in an emergency situation other radionuclides like Pu-241 or Am-241 may be of interest as well. Moreover, for the evaluation of the exposure situation it is also important to analyze these radionuclides in other...

26. AN INNOVATIVE METHOD FOR DETERMINATION OF URANIUM ISOTOPES IN SOILS BY ALPHA-SPECTROMETRY COUPLED WITH MICROTHENE-TOPO COLUMN

Dr Guogang Jia (Ispettorato Nazionale per la Sicurezza Nucleare e la Radioprotezione)

Radiochemistry

Oral Presentation

Determination of the low-level activity concentrations of uranium isotopes in soil samples are very important in many fields, including nuclear industry, environmental science, radioecology, geology and geochronology. As early as 2002, our laboratory has started to develop a method for determination of uranium isotopes by α-spectrometry in soil samples, which was based on fusion with...

73. DETERMINATION OF PO-210 IN DRINKING WATER WITH PLASTIC SCINTILLATION RESINS. DEVELOPMENT AND METHODS COMPARATIVE

Alex Tarancón

Radiochemistry

Oral Presentation

Po-210 is a natural occurring radionuclide produced in the decay chain of ²³⁸U. Spanish legislation RD 140/2003 establishes that all consumption waters which exceeds fixed parametric values requires the determination of ²¹⁰Po, among other specific radionuclides. In addition, due to its extremely high radiotoxicity the limit activity allowed for ²¹⁰Po, 0.1 Bq...
