Zusammenfassung:The invention provides a 238PU source preparation technology with low radiation dose, long service life and good electrostatic eliminating effects. The preparation technology comprises steps of mixing, molding, sintering, rolling, secondary solid and secondary active band preparation, cubic solid preparation and product source tape rolling; wherein the maxing step is that the 238PuO2 and the Au powder are mixed in a weight ratio of 1:14 to 1:20; the molding is carried out under a pressure of 1.5 to 2t/cm2 and the sintering is under 650 to 1000 DEG C.
