  • Title: Preparation and activity measurement of electrodeposited alpha-emitting sources.
    Author: Lee KB, Man Lee J, Soon Park T, Oh PJ.
    Journal: Appl Radiat Isot; 2006; 64(10-11):1260-4. PubMed ID: 16891121.
    Abstract:
    Alpha-emitting 238Pu and 241Am sources on stainless steel substrates have been prepared using a new electrodeposition method based on an ammonium oxalate-ammonium sulfate electrolyte containing diethyl triamino pentaacetic acid. The deposition yield is determined by measuring the activity of the sources using a high-efficiency 2pi alpha proportional counter and a backscattering chamber designed and fabricated for this purpose. Optimal electrodeposition parameters have been determined for 241Am, enabling manufacture of standard alpha-emitting sources with minimal radioactive waste.
