Abstract
The influence of several parameters including voltage ,time ,acidity ,inter‐electrode distance and plating pen movement speed on the plating efficiency were investigated using homemade equipments ,and the optimal parameters with the efficien‐cy better than 85% were confirmed . Using those parameters ,90 Sr‐90 Y β radioactive sources with sizes of 300 cm2 (13 cm × 24 cm) ,600 cm2 (15 cm × 38 cm) and 1 000 cm2 (25 cm × 38 cm) were prepared .The results show that the uniformity of the sources is better than 10% ,and the well stability indicates the potential application for the calibra‐tion of surface contamination meters .关键词
