title: Production of reference sources of radioactive aerosols in filters for proficiency testing.
abstract: In the framework of the organization of proficiency testing, filters with deposits of137Cs and90Sr+90Y radioactive aerosols have been submitted to laboratories for radionuclide measurement. Procedures for the special preparation and characterization of filters have been developed. The different steps of filter preparation, determination of the deposited radionuclide activity and characterization of the homogeneity of these deposits are presented. This method of filter preparation can also be used in the production of secondary standards, whose properties are more adapted to the needs of laboratories measuring radioactivity in filters than are the solid sources that they typically use.
