<![CDATA[OPTIMIZATION OF ELECTRODEPOSITION PROCESS FOR 242Pu MEASUREMENT BY ALPHA SPECTROMETRY. In this study electrodeposition method was used to design and set up an electrodeposition device for 242Pu source preparation for measurement by alpha spectrometry. The purpose of this study was to determine the optimal electrodeposition process parameters so as to obtain 242Pu alpha sources with good spectrum properties and maximum result from source preparation by electrodeposition process. Standard samples of 242Pu with specific activity were prepared from plutonium standard aqueous solution. Experiments were conducted to determine the main parameters that have significant influence on the deposition efficiency. The electrodeposition process parameters analyzed were the effects of time, electric current and anode-cathode distance using an electrolyte solution of ammonium sulphate at pH 3.5. The results of the optimization of the electrodeposition process were optimal time of 2.5 hours, electric current of 1.4A and cathode- anode distance of 10 mm. These parameters' values are the best conditions for the deposition of 242Pu. Alpha measurement results of the electrodeposited source of 242Pu also show good spectrawith electrodeposition process reproductibility of 95.3%.]]>
