In order to offer the high resolution 241 Am alpha source used in the real-time monitoring of nuclear power plant safety operation,the magnetohydrodynamic electrodeposition method was built,and the equipment and processes were designed.The241 Am sources were prepared by this method,and the deposition conditions were optimized.The optimal deposition conditions are as follows:(NH4)2 SO4 concentration is0.5 mol/L as deposition solution,the current density is 180 mA/cm2,the distance between platinum anode and s...
