The volatile radioactive nuclides produced by thermal neutron fissioning of uranium oxide-polyethylene fuel of the AGN-201 Reactor were collected in an evacuated aluminum cylinder. The following constituent isotopes, identified by gamma ray spectrometry, present in 20 minute old gas are; Te¹³¹, Xe¹³¹ ͫ, Xe¹³³ ͫ , Xe¹³³, Xe¹³⁵ ͫ, Xe¹³⁷, Xe¹³⁸, Xe¹³⁹, Se⁸¹, Se⁸³, Kr⁸⁵ͫ , Kr⁸⁵, Kr⁸⁷, Kr⁸⁸, and Kr⁸⁹. Radioactive daughter products identified are Cs¹³⁷, Cs¹³⁸, Cs¹³⁹, Rb⁸⁸, Rb⁸⁹, and I¹³¹. Other isotopes of iodine, tellurium, and bromine may be present. Spectra were taken with NaI (Th) scintillation crystal.
