Abstract  

A simple procedure is described for the fabrication of mCi level strong sources of147Pm radioisotope on a noble metal substrate like Palladium as a source for β-ray thickness gauge. The procedure is based on the principle of internal electro-deposition of147Pm from aqueous solutions containing147Pm3+ ions, using metallic magnesium for the purpose. Investigations conducted towards ascertaining the adherence of the147Pm radioactivity onto the palladium substrate. Leaching studies conducted on these source indicated that the radioactive film is satisfactorily adherent to the palladium substrate, suggesting that the method can be used for fabricating satisfactorily safe high β-activity sources of147Pm contained in small active dimensions. Results of leaching studies keeping the sources fully immersed in boiling water for 15 minutes are also presented.
