The purified plutonium 3290700100013 solution was titrated and dried to prepare the 3290700100014 silica-encapsulated plutonium target. 3290700100015 DETECTOR (HPGE) A coaxial HPGe detector. The efficiency of the 3290700100016 detector was calibrated using 152Eu, 133Ba, 182Ta, 3290700100017 124Sb and 24Na standard sources. 3290700100018 METHOD (FPGAM,RELFY) Gamma-ray nondestructive method for the 3290700100019 yield of 88Kr relative to 99Mo, and the yields of 3290700100020 85mKr and 87Kr relative to 88Kr.
