Corina Anca Simion, Niculina Paunescu, Nicolae Mocanu, Marian Romeo Calin, Sorin Bercea, and Bogdan Mitrica. ULTRA LOW RADIATION BACKGROUND LSC MEASUREMENTS IN A SALT MINE: A FEASIBILITY STUDY. In 10th International Symposium on the Synthesis and Applications of Isotopes and Isotopically Labelled Compounds--New Analytical Methods, JOURNAL OF LABELLED COMPOUNDS & RADIOPHARMACEUTICALS, 53, pp. 307-311. 2010.

Abstract: Measurements of long-life radionuclides are developing worldwide by radiometric techniques and mass spectrometry
methods too. Both methods offer advantages and disadvantages. In tandem, AMS and LSC techniques provide a powerful working
tool. So the techniques provide comparable data for the same types of samples and can support each other in creating a database
for a given area, such as the area of Romania. Moreover, ultra low level LSC may be an additional tool for continuous monitoring of
environmental conditions in which AMS is current used to measuring the concentration of different contaminants in the air with a
high degree of accuracy. To compare the results of applying the above-mentioned techniques, we proposed an analysis of the ideal
operational conditions for an ultra low level scintillation spectrometer Quantulus 1220 in two situations: at the surface (IFIN-HH
location, where nuclear activities are performed) and underground in a salt mine. The paper presents in detail the scientific and
technical aspects as well as predictions on reducing the measurement background with depth, compared with other similar
experiments in Europe.

Keywords: ultra low level liquid scintillation counting, underground laboratory, salt mine
