An electrochemical pathway to prepare circular planar 90Sr/90Y sources for the calibration of surface contamination monitors

Abstract

In this communication, we describe a novel method to prepare circular planar 90 Sr/ 90 Y sources (/ = 16 mm) exploiting the intrinsic properties of the anodized titanium to electro-deposit predicted quantity of 90 Sr activity from an aqueous solution. The influences of various experimental parameters such as pH of the electrolyte, applied current density, electrodeposition time and carrier strontium concentration were thoroughly investigated to arrive at a condition resulting optimal deposition of the 90 Sr/ 90 Y activity on the substrate. An optimized electrochemical procedure to prepare *3.7 MBq (*0.1 mCi) of circular planar 90 Sr/ 90 Y sources commensurate with regulatory safety requirement has been the positive outcome.
