The design and installation of irradiation facilities for the NBS Reactor are described, and studies of the operating characteristics of the pneumatic tube facilities have begun. Procedures have been developed for determining molybdenum in the presence of large amounts of tungsten and for the determination of uranium. Methods for determining a contamination free blank for applipation to liquid samples, a study of the application of neutron activation to the analysis of stained glass were begun. The application of thermal and fast neutron activation analysis and photonuclear activation analysis to the NBS Standard Reference Material program is discussed. Studies of the application of 3-MeV neutrons from a Cockcroft-Walton neutron generator to activation analysis and of the 3-MeV neutron buildup in 14-MeV neutron activation has been studied. The determination of carbon by photonuclear activation has been-extended to various metals other than sodium, thallium has been determined in glass samples by photon bombardment and the photofission of thallium, bismuth and lead has been studied. Hydrated antimony pentoxide has been used to separate sodium from glass samples for subsequent instrumental activation analysis, and the antibiotic, tetracycline, has been applied to radiochemical separations.
