Summary:Ion migration spectrometry technology is an effective method for rapid detection of chemical warfare agents in the field. 63Ni source for poision alarm is a common ionization source because of its advantages of no maintenance and safe use. In this paper, the preparation method of 63Ni source for poision alarm was studied, and the activity measuring device and electroplating device were designed. The most important is to study the parameters of electroplating process, so as to determine the best electroplating conditions are temperature 20 ℃, current density 20 mA/cm2, pH 2-3, electroplating time 10 min. Finally, parallelism experiment and fastness test were carried out. The results show that the qualified rate of primary electroplating of the radioactive source prepared by this method can reach 100% and the coating and nickel sheet are firmly bonded. The radioactive source prepared by this method can meet the requirements of ion migration spectrometry technology.
