Improvements in quantitative source preparation
Quantitative source preparation is indispensable for radionuclide standardisation. 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 alpha-particle spectra.
