Abstract:
This paper describes an electrochemical method for deposition of a thin layer of (57)Co on the outer surface of a copper sphere of 5mm diameter intended to be used as a point radioactive source. A description of the electrolytic cell, the process of deposition and the assay of the (57)Co activity are presented. About 1.48MBq (∼40μCi) of (57)Co could be deposited using the described method. The quality of the prepared source in terms of nonleachability, uniform distribution of activity and stability, which are necessary attributes to be ensured before application were evaluated and found to be satisfactory.
