Quantitative source preparation is indispensable for radionticlide standardization. To improve the source quality. a device has been developed to accelerate the evaporation of solvents from a drop deposited on a substrate. Short drying times were reached by stirring the rotating drop with multiple jets of dry nitrogen at elevated temperature. Uniform deposits with a large number of small crystals were obtained. The source-quality was checked by micrographs and scans of autoradiographs and by the shape parameters of Y-particle spectra. 2000 Elsevier Science Ltd. All rights reserved.
