UJI PRODUKSI Mo-99 HASIL FISI DENGAN BAHAN SASARAN FOIL LEU BUATAN P2TBDU-BATAN. Selama ini telah dilaksanakan beberapa kali produksi Mo-99 dengan menggunakan bahan sasaran foil LEU buatan Argonne National Laboratory (ANL). Dalam produksi Mo-99 dengan proses Cintichem yang dimodifikasibahan sasaran foil LEU sangat menentukan. Telah dilakukan uji produksi Mo-99 hasil fisi dengan bahan sasaran foil LEU (LEU, < 20% U-235) buatan P2TBDU-BATAN dengan proses Cintichem yang dimodifikasi, meliputi pelarutan foil LEU menggunakan HNO3 9,5N, penarikan gas iodium, proses pemisahan dengan pengendapan α-Benzoin Oxime dan pemurnian Mo-99 melalui kolom kromatografi. Foil LEU larut dengan sempurna selama 30 menit dan penarikan gas iodium dilakukan dengan pendinginan nitrogen cair. Setelah melalui tahap pemisahan (pengendapan) dan pemurnian kolom I dan kolom II radionuklida pengotor masih besar dan aktivitas pengotor pemancar α melebihi persyaratan standard internasional yang ditetapkan yaitu sebesar 7.716E-7 µCi/mCi Mo-99.

PRODUCTION TEST OF Mo-99 FISSION PRODUCT USING LEU TARGET FOIL MADE IN P2TBDU – BATAN. Production of Mo-99 fission product using LEU target foil of Argonne National Laboratory (ANL) has been performed several times recently in BATAN. In the production of Mo-99 using modified Cinthichem method, the LEU target foil was very critical. This paper reported production test on Mo-99 fission product using LEU target foil ( LEU < 20% U-235) made by P2TBDU – BATAN using modified Cintichem method. The process included dissolving of LEU foil with 9.5 N HNO3, suctioning of iodine gas, separation process using precipitation with α–benzoin oxime, and purification by column chromatography. The LEU foil was completely dissolved after 30 minutes and gas suction was performed by cooling with liquid nitrogen. After separation and two purification steps, the radionuclide impurities were remained high and activity of αimpurities exceeded international standard requirements, i.e. 7.716E-7 µCi/mCi Mo-99.
Key words: Production of Mo-99 FP, Target foil LEU P2TBDU
