Interest in developing an economically competitive activation method for analysis of lead in paint prompted studies on the evaluation of a small /sup 252/ Cf source for this determination. The reaction /sup 204/Pb(n,n')/sup 204m/Pb was studied first. All three gamma lines of /sup 204m/Pb were adequately resolved with a Ge(Li) detector, with no interference from other major or minor constituents. Results of studies on the /sup 207/Pb(n,n')/sup 207m/Pb reactions were not as reliable as those with the /sup 204m/Pb isotope. Results indicate that with a /sup 252/Cf source of several tens of milligrams and the 60cm/sup 3/ Ge(Li) detector, the determination of ~1% of Pb in a sample of 1 to 2 grams of paint could be accomplished with a 15 min irradiation and 15 min counting.
